HTML to latex: Controlling table column width

Hi, 

I am converting HTML tables to latex. Problems arise if the table is large 
and has many columns.
This table's cols add up to 99%,
```
<table class="table table-bordered table-sm small" style="width: 100%;">
  <colgroup>        
    <col width="14%">
    <col width="6%">            
    <col width="6%">              
    <col width="20%">                
    <col width="11%">                  
    <col width="13%">                    
    <col width="7%">                      
    <col width="7%">                        
    <col width="15%">                        
    </colgroup>    
    <thead>   
    <tr>
        <th>Risiko (Beschreibung)</th>
        <th>Eintritts­wahr­schein­lichkeit</th>
        <th>Netto-Schadens­höhe</th>
        <th>Durchzuführende Gegenmaßnahmen</th>
        <th>Frühwarn­indikator</th>
        <th>Schwellwert</th>
        <th>Beob­achtungs­intervall</th>
        <th>Risiko­verantwort­licher</th>
        <th>Anmerkungen</th>
    </tr>
    </thead>
    <tbody>
    <tr>
        <td>(Einzel)-Kundenausfall<br>(bla bla blabla dasdf)</td>
        <td>mittel</td>
        <td>&lt; 1 T€</td>
        <td>a) Beauftragung eines Inkassounternehmens zur Beitreibung der

        <td>Automatisch durch Software<br>Report an GF</td>
        <td>siehe Handbuch Kapitel Adressausfallrisiko</td>
    </tr>
</table>
```
but the resulting minipages only have 75% \columnwidth. I know that there 
is other spacing for the grid necessary, but especially now with 8 columns 
any space is important.

What can I do here to get full width tables.

Thank you all in advance!

Re: HTML to latex: Controlling table column width

[John MacFarlane]

We apply a (0.97)^n "scale factor" to make room for space between
columns, where n = the number of columns.

Looks like this gives bad results when n is large.  So this
formula needs to be tweaked.  Suggestions welcome. I don't
actually remember why we (I?) chose to make the scale factor
depend on the number of columns in this way, but it may have
been by experimenting...I assume I tried a constant factor
first and it didn't work.

I just tried your document (using pandoc -s)
and with the default latex template the table actually overflows
the textwidth.  I assume you're using very wide margins or a very
small font?

Even with 1 inch margins and 10pt font, the table takes up
nearly the whole textwidth and the contents are too wide for
the cells.  Only in landscape mode can I make it fit --
and then it actually looks pretty good, except for one
overlapping cell.

Relevant code is around l.854 of the LaTeX writer.

Re: HTML to latex: Controlling table column width

['Oliver Demetz' via pandoc-discuss]

[-- Attachment #1.1: Type: text/plain, Size: 7824 bytes --]

Thanks for your reply. 

Yes I am typesetting this in landscape. However, in any page orientation, 
the minipages only occupy 0.75 \columnwidth.

In my typesetted result, the table has roughly 20 cm width on a a4 
landscape page (which has 30cm of width). 

Concerning the current 0.97^n factor: In my case 0.97^9 = 0.76, so that's 
where my problem comes from.
Shouldn't it be possible to calculate the required spacing of the 
tabular/longtable explicitly? I remember variables like \tabcolsep.
The n columns have (n-1) inner separations, so it should be more accurate 
to compute <complete-width> - (n-1)<space-one-seaparation-needs>, and 
distribute this over all columns.

Yes.  But this sum NEEDS to be less than columnwidth because of
spaces between columns.

Well, LaTeX could calculate this, because it knows the settings
of such variables.  Pandoc doesn't. Can we specify minipage width as
{0.17\textwidth - \tablecolsep}?  That could work; I'm going to
try it.

I tried this.  It almost works.  You need the latex calc package
for this.  For a 5-column table I set widths like this;

\begin{minipage}[t]{\columnwidth - 4\tabcolsep) * \real{0.15}}

That should be correct, but it gives a table that is still a
bit wider than the columnwidth.  So somewhere there is space
inserted beyond just the tabcolsep, I guess. Does anybody know
how to calculate the correct number?

Think I figured it out.
https://tex.stackexchange.com/questions/425228/cant-properly-calculate-column-width
"By default each column is surrounded by one \tabcolsep on each
side (resulting in two such spaces when two columns are side by
side)."

We suppress the seps on the edges, so we should have
2(n-1) tabcolseps in all where n is the number of columns.

This works! I will make the change.

Dear John,
you said you'd make the change. I could not find a corresponding commit on 
github. So have you done it already or may I kindly remember you to realize 
this change? It would be of great help for me! 

I am very grateful for your efforts.

Thanks!

Often the problem with too  wide tables is that the column headers are wide
while the contents of the regular rows are not. In such a case a useful
LaTeX trick is to rotate the header contents and remove / reduce their
nominal width so that they appear slanted with a reasonable amount of
whitespace around them. With Pandoc I nowadays use a custom box command
defined through the adjustbox package and a filter to inject that command
into the column headers. The LaTeX part is, thanks to the work of the
author of the adjustbox package, very easy and clean:

``````latex
\usepackage{adjustbox}

\newadjustboxcmd{\aH}{scale=0.85,rotate=60,left=1em}

% \let\toprule\relax
% \let\bottomrule\relax
``````

Note that the order of the parameters in the `\newadjustboxcmd` definition
is significant! `left=1em` left-aligns the content in the box *and* sets
the width of the box — both crucial. You may want to remove the scaling,
but I think it looks slightly better with it.

I then use a Lua filter to "wrap" the header contents in this command, and
at the same time setting the nominal column widths to zero so as to make
the width "automatic", i.e. LaTeX decides the widths. Note that this filter
presupposes that the table can successfully be converted to and from a
SimpleTable!

``````lua
-- LaTeX injects, to be reused.
local pre = pandoc.RawInline('latex', '\\aH{')
local post = pandoc.RawInline('latex', '}')

function Table (tab)
  -- Convert the complex Table into a SimpleTable
  local simple = pandoc.utils.to_simple_table(tab)
  -- Inject LaTeX code into the headers
  for _,head in ipairs(simple.headers) do
  -- Check that the header contains only one block
    if #head == 1 then
      -- Check that that block is a Para or Plain
      if 'Para' == head[1].tag or 'Plain' == head[1].tag then
        -- Insert the LaTeX before...
        table.insert(head[1].content, 1, pre)
        -- ...and after the Para/Plain content
        table.insert(head[1].content, post)
      end
    end
  end
  -- Reset column widths
  for i=1, #simple.widths do
    simple.widths[i] = 0.0
  end
  return pandoc.utils.from_simple_table(simple)
end
``````

The result can be seen in the attached PDF. You may want to remove the top
and bottom rules from tables to make this look better. To do so just
uncomment the two commented lines in the LaTeX snippet above.

Copy the LaTeX snippet in a file `adjust-table-head.ltx` and the Lua code
in a file `adjust-table-head.lua` and then add `-L adjust-table-head.lua -H
adjust-table-head.ltx`  to the pandoc command line.

Re: HTML to latex: Controlling table column width

['Oliver Demetz' via pandoc-discuss]

[-- Attachment #1.1: Type: text/plain, Size: 10497 bytes --]

This is incredible! 

Two questions:
1. how is this filter applied? To every table? Could I tweak it to just be 
applied to tables with more than, say, 6 columns?
2. If I predefine my relative column widths using a <colgroup>, then I 
think the result is always a complex table, right? So in this case, I 
cannot use this approach?

Thank you both, BPJ and John, you are just great!

Absolutely. Just below the line with the to_simple_table() conversion add
this:

``````lua
-- Check how many columns there are.
if #simple.widths < 7 then return nil end
``````

with 7 adjusted as needed

2. If I predefine my relative column widths using a <colgroup>, then I

I don't know. Possibly the conversion function just throws out what doesn't
fit. I think Albert can answer that.
The approach *can* probably be used with complex tables, but that would be
considerably more hairy, and I haven't got figured it out yet.

Just using such tricks as I have accumulated over the years.

BTW you can now do the header-slanting trick with CSS!

It's just some CSS using rotate(-60), some negative padding and some extra
padding at the top of the table to make room for the rotated text, and of

See the attached files.  Of course getting it to *really* work was 
harder than I remembered...

    We need to set a padding above the table to make room
    for the rotated headers.

    Unfortunately the right amount of padding-top depends
    on the actual width of the widest column header text,
    so if possible you probably want to hard code a class/id
    or even a style attribute on the wrapping div and set the
    padding based on that.

    For the Pandoc filter solution I currently heuristically
    calculate a padding in ems from on the number of chars
    in the widest column header multiplied by a (fraction)
    factor and set a padding in a style attribute based on
    that. The factor can be modified by setting the metadata
    field `rotate_tab_heads_padding_factor` or the environment
    variable `PDC_ROTATE_TAB_HEADS_PADDING_FACTOR` to the
    desired factor. Not ideal but it works reasonably well

Right. Internally, all tables are complex tables. What `to_simple_table`
does is to call the same function that pandoc uses internally when
rendering output in formats which don't support complex tables. So some
info like colspans will be lost, but most info should make it through.
Relative column width should be retained fine.

Extremely cool filter btw! I wish I had known about this two months ago
when I was fighting to format tables in LaTeX.

So what happens when there is colspan/rowspan, do you get rows which are
shorter than the overall number of columns (which I think Pandoc used to
barf at) or are empty cells inserted to compensate? Back in the day I wrote
a Perl script which inserted empty cells like that before feeding HTML
tables to Pandoc. It was kind of tricky to keep track of rowspans. I did
two passes over the rows; one to splice in empty cells to compensate for
colspans, with rowspans copied from the original cells, then another to
splice in empty cells in the rows below for cells which had rowspan.
Something like

``````perl
for my $r (0 .. @$rows) {    # row index
    for my $c ( 0 .. $#{$rows->[$r]}) {    # col index
        my $cell = $rows->[$r][$c];
        next unless $cell->{rowspan};
        my $clone = {%$cell};
        $clone->{rowspan} = $cell->{rowspan} - 1;
        splice @{$rows->[$r+1]}, $c, 0, $clone;
    }
}
``````

Kind of hairy!

Thanks! It seems LaTeX injection has become my specialty.
