Feature Request: Support spreadtab block

[Hzbeta]

Spreadtab allows us to construct tables in a manner similar to a spreadsheet. The cells of a table have row and column indices and these can be used in formulas to generate values in other cells. Detailed instructions can be found here.

I hope latexindent.pl can support formatting of the table content in spreadtab block, just like normal tabular block!

For example, no yaml setting, original .tex code

\begin{spreadtab}{{tabular}{r*6c}} % or \spreadtab{{tabular}{r*6c}}
@Ages & 10 & 11 & 12 & 13 & 14 & 15\\
@Number & 5 & 8 & 20 & 55 & 9 & 3\\\hline
@Average&\multicolumn{6}{l}{:={sumprod(b1:g1;b2:g2)/sum(b2:g2)}}
\end{spreadtab} % or \endspreadtab

actual/given output

\begin{spreadtab}{{tabular}{r*6c}} % or \spreadtab{{tabular}{r*6c}}
    @Ages & 10 & 11 & 12 & 13 & 14 & 15\\
    @Number & 5 & 8 & 20 & 55 & 9 & 3\\\hline
    @Average&\multicolumn{6}{l}{:={sumprod(b1:g1;b2:g2)/sum(b2:g2)}}
\end{spreadtab} % or \endspreadtab 

desired or expected output

\begin{spreadtab}{{tabular}{r*6c}} % or \spreadtab{{tabular}{r*6c}}
    @Ages    & 10                                                      & 11 & 12 & 13 & 14 & 15 \\
    @Number  & 5                                                       & 8  & 20 & 55 & 9  & 3  \\\hline
    @Average & \multicolumn{6}{l}{:={sumprod(b1:g1;b2:g2)/sum(b2:g2)}}
\end{spreadtab} % or \endspreadtab 

anything else

Thanks for such a great LaTeX formatting tool! :)

Great, thanks, will do :)

If anyone wants to take this on, it should just be adding spreadtab to the lookForAlignDelims field. Should be a nice way to get started on contributing.

This is implemented as of 8e089c5

It'll be part of the next release. Please leave this issue open until I've made the release, hopefully coming soon...
