Hello Thanks to advice received in this list orgtbl-to-latex does precisely what I want, it generates a latex table with boundaries and hlines. Here is an example
% BEGIN RECEIVE ORGTBL this \begin{tabular}{|l|l|} this & that\\ \hline this & that\\ \hline \end{tabular} % END RECEIVE ORGTBL this \begin{comment} #+ORGTBL: SEND this orgtbl-to-latex :lend "\\\\ \\hline" :environment tabular | / | <> | <> | | | this | that | | | this | that | \end{comment} Now I would like to have the same for orgtbl-to-html but the standard configuration gives <!-- BEGIN RECEIVE ORGTBL this --> <table border="2" cellspacing="0" cellpadding="6" rules="groups" frame="hsides"> <colgroup> <col class="org-left" /> </colgroup> <colgroup> <col class="org-left" /> </colgroup> <tbody> <tr> <td class="org-left">this</td> <td class="org-left">that</td> </tr> <tr> <td class="org-left">this</td> <td class="org-left">that</td> </tr> </tbody> </table> <!-- END RECEIVE ORGTBL this --> <!-- #+ORGTBL: SEND this orgtbl-to-html :splice nil :skip 0 | / | <> | <> | | | this | that | | | this | that | --> However the produced table did not contain outer boundaries nor horizonal lines. I presume I have to change #+ORGTBL: SEND this orgtbl-to-html :splice nil :skip 0 to something else, but what? I googled for quite a while. thanks Uwe Brauer
