how to make tex4ht center a long table as it does with table?












3















when using centering option in table, and then using either tabular or longtable then both come out centered in PDF as expected.



But in tex4ht, only the tabular comes out centered in middle of the web page, while the longtable is not centered and remained to the left edge of the webpage.



Here is a MWE



documentclass[11pt]{article}%
usepackage{float}
usepackage{longtable}
begin{document}

This is my table

begin{table}[H]
centering
begin{tabular}[c]{|c|c|}hline
A & B \hline
853.075 (sec) & 43.711 (sec)\hline
14.218 (minutes) & 0.729 (minutes)\hline
end{tabular}
%caption{Total real time used to solve all problems}
end{table}

my table is done

This is my long table

begin{longtable}[c]{|c|c|}hline
A & B \hline
853.075 (sec) & 43.711 (sec)\hline
14.218 (minutes) & 0.729 (minutes)\hline
end{longtable}

my long table is done

end{document}


Compiled using lualatex foo.tex shows that both are centered in middle of page

Using make4ht foo.tex "htm" only the tabular is centered:

How to make longtable be centered as well?

  • centering has no effect on a longtable and a longtable inside a table can not do anything useful, so remove the begin[table}[H] and centering.

  • but you added begin{center} which also does nothing useful for longtable.

This is easy to fix using bit CSS:



Preamble{xhtml}
Css{table.longtable{margin-left: auto;margin-right:auto;}}
begin{document}
EndPreamble


The result:
