orgtbl-to-latex and orgtbl-to-html with boundaries and line

[Uwe Brauer <oub@mat.ucm.es>]

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
