Can one put individual horizontal and vertical lines between rows/columns in xtable? Just like for example \HL in \starttable?

The workings of parameter spaceinbetween on \startxtable remain a mystery to me. Can someone enlighten me?

You can use MetaPost to draw the rules but it’s awkward because you can make a setup like this

  \setuxptable[column][1][background=…]

which is only supported by natural tables. It would be simpler when stables had a counter like \currentxtablecolumn
which could be accessed to make a test like “if \currentxtablecolumn = 1 then … fi” but this isn’t the case.

It inserts a space between each row, the amount of space is the same as \blank[…] would insert.

\starttext

\startxtable[spaceinbetween=line]
  \startxrow
    \startxcell A \stopxcell
    \startxcell B \stopxcell
  \stopxrow
  \startxrow
    \startxcell C \stopxcell
    \startxcell D \stopxcell
  \stopxrow
  \startxrow
    \startxcell E \stopxcell
    \startxcell F \stopxcell
  \stopxrow
\stopxtable

\stoptext

I see. No hope here. 

But I found some sort of solution which I communicate here. It is bit of a kludge but does more or less what I had in mind. The following macros do the work in my xml=>xtable module:
<table frameon="t,b"> also <thead> <tr> <td> and so on.

\def\setframeparts#1#2#3{%
\doifinset{t}{#1}{#3[topframe=#2]}%
\doifinset{b}{#1}{#3[bottomframe=#2]}%
\doifinset{l}{#1}{#3[leftframe=#2]}%
\doifinset{r}{#1}{#3[rightframe=#2]}%
}
..#2 being \setupxtable or \setupframed, just as needed
\doifnot{\xmlatt{#1}{frameon}}{\empty}%
    {#2[frame=off]\setframeparts{\xmlatt{#1}{frameon}}{on}{#2}}%
\doifnot{\xmlatt{#1}{frameoff}}{\empty}%
    {#2[frame=on]\setframeparts{\xmlatt{#1}{frameoff}}{off}{#2}}%
..

Do I conclude correctly that the dimension of the space is fixed to what \blank[] does? 
I experimented with various values, but did not get much out of it.

Can make a working minimal example. As you use xml as input language it’s no problem to save some settings and apply them later to each cell which will allow you to set different values for the frames.

You should also know that each xtable cell is a framed (it uses the \framed code) like natural tables and \setupxtable accepts the same arguments as \setupframed.

I’m sorry but I was wrong, the “spaceinbetween” value isn’t passed to \blank but context expects here something like “spaceinbetween={\vskip <dimension>}”. I can send a patch to Hans because a internal blank would be allow you to write “spaceinbetween=1cm” or “spaceinbetween=2*line”.

I knew already, which is what me did develop the macros. No need to give complete examples, I think. The intention was to give you an impression of the solution, just in case you should be curious.
Using a macro argument for the \setup.. is meant to apply this code to both xtable and framed.

I would very much appreciate that. It seems most natural to have a dimension here and thenit will work in the same manner as columndistance. Thanks in advance.
