tabulate inside itemize

tabulate inside itemize

[Mike Cooper]

[-- Attachment #1.1.1: Type: text/plain, Size: 1955 bytes --]

I would normally use tab stops and line breaks to achieve the following in a numbered list:

1.  DC     =  3.20 bbl =   420 ft
    HWDP   =  3.90 bbl =   450 ft
    DP     = 34.63 bbl = 2,037 ft
    Totals = 41.73 bbl = 2,907 ft

2.  [next step …]


This is what I tried, but the output has a blank line at the number.  I can’t find anything about tabulate inside itemize.

\starttext

\startitemize[n]
            \startitem \starttabulate[|l|l|r|l|r|]
                                    \NC DC \NC = \NC 3.20 bbl \NC = \NC 420 ft \NC \NR
                                    \NC HWDP \NC = \NC 3.90 bbl \NC = \NC 450 ft \NC \NR
                                    \NC DP \NC = \NC 34.63 bbl \NC =  \NC 2,037 ft \NC \NR
                                    \NC DC \NC = \NC 41.73 bbl \NC =  \NC 2,907 ft \NC \NR
                                    \stoptabulate \stopitem
            \startitem Convert 2,907 to TVD: \\TVD = 2,907 × cosine 45° = 2,907 × 0.707 = 2,056 ft \stopitem
            \startitem ΔP = 2,056 ft × 0.052 × (15 - 7.2) = 834 psi
\stopitemize

\stoptext

Is there some way to stop the blank line or should I use an entirely different approach?

THANKS!!

1. Use \blank[overlay] to continue on the first line of the item entry

2. Disable the blank line at the start of the table with "before="

\starttext

\startitemize[n]
     \startitem \blank[overlay]
         \starttabulate[|l|c|r|c|r|][before=,after=]
         \NC DC   \NC = \NC  3.20 bbl \NC = \NC   420 ft \NC\NR
         \NC HWDP \NC = \NC  3.90 bbl \NC = \NC   450 ft \NC\NR
         \NC DP   \NC = \NC 34.63 bbl \NC = \NC 2,037 ft \NC\NR
         \NC DC   \NC = \NC 41.73 bbl \NC = \NC 2,907 ft \NC\NR
         \stoptabulate
     \stopitem
     \startitem
         Convert 2,907 to TVD:\crlf
         TVD = 2,907 × cosine 45° = 2,907 × 0.707 = 2,056 ft
     \stopitem
     \startitem
         ΔP = 2,056 ft × 0.052 × (15 – 7.2) = 834 psi
     \stopitem
\stopitemize

\stoptext


You can also get rid of the = in your table when you use the \EQ column 
separator and set the sign for the separator to =.

\starttext

\starttabulate[|l|r|r|][EQ={=}]
\NC DC   \EQ  3.20 bbl \EQ   420 ft \NC\NR
\NC HWDP \EQ  3.90 bbl \EQ   450 ft \NC\NR
\NC DP   \EQ 34.63 bbl \EQ 2,037 ft \NC\NR
\NC DC   \EQ 41.73 bbl \EQ 2,907 ft \NC\NR
\stoptabulate

\stoptext

I know this looks terrible:

\define\MyTabulateHack{\vskip-\lineheight\blank[disable]}

\startitemize[n]

     \startitem \MyTabulateHack
     \starttabulate[|l|l|r|l|r|]

but it kind of works ok in your case.

Naive solution: Add a \hbox around tabulate:


\defineframed[tabulateframed][location=top,frame=off]

\starttext

\startitemize[n]
             \startitem \dontleavehmode
               \tabulateframed{\starttabulate[|l|l|r|l|r|]
                                     \NC DC \NC = \NC 3.20 bbl \NC = \NC 420 ft \NC \NR
                                     \NC HWDP \NC = \NC 3.90 bbl \NC = \NC 450 ft \NC \NR
                                     \NC DP \NC = \NC 34.63 bbl \NC =  \NC 2,037 ft \NC \NR
                                     \NC DC \NC = \NC 41.73 bbl \NC =  \NC 2,907 ft \NC \NR
                                     \stoptabulate} \stopitem
             \startitem Convert 2,907 to TVD: \\TVD = 2,907 × cosine 45° = 2,907 × 0.707 = 2,056 ft \stopitem
             \startitem ΔP = 2,056 ft × 0.052 × (15 - 7.2) = 834 psi
\stopitemize

\stoptext

Normally, you can fix such issues by appending a \dontleavehmode in front of the command but that doesn't work here. The offending code is line 1300 of tabl-tbl.mkxl:

\unexpanded\def\tabl_tabulate_outside_before
   {\ifhmode\par\fi
    \ifhmode
      \vbox\bgroup
      \let\tabl_tabulate_outside_after    \egroup
      \let\tabl_tabulate_outside_inbetween\relax
    \orelse\ifinner
      \let\tabl_tabulate_outside_after    \relax
      \let\tabl_tabulate_outside_inbetween\relax
    \else
      \whitespace
      \tabulationparameter\c!before
      \relax
      \let\tabl_tabulate_outside_after    \tabl_tabulate_outside_after_indeed
      \let\tabl_tabulate_outside_inbetween\tabl_tabulate_outside_inbetween_indeed
    \fi}
\protect

When you use \dontleavehmode\starttabulate, \starttabulate starts in horizontal mode but the first \par in the above command takes it back to vertical mode. The next \ifhmode then evaluates to false, \ifinner also evaluates to false, so we enter the \else loop which inserts a \whitespace.

The reason why adding a \hbox{...} (which is what \framed without an align key does) works is because inside an \hbox{...} \par doesn't take TeX back to vertical mode. So, we enter the first branch.

Ah ... I start forgetting things ... bad ... (I should use tex more

I got Wolfgang's solution first and it works great.
But I think there are some things in your solution that I should try to learn about.  :)
