Hi

Thanks ... you made my day ... even if haven't asked for displaying 2
tables (or maybe even more) at the same time with all the Datatables
magic glue in ORG syntax this was exactly what I would have asked next
... Yeeeeah your solution (even with the id attribute) works perfectly.

But back to the main question ... is it somehow possible to generate the
<tfoot> footer elements (I just realized that my example was actually
wrong, I used <thead> for <tfoot>... it should look like the following

#+attr_html: :id example :class cell-border hover compact :width 100%
| Name        | Position         | Office        |
|-------------+------------------+---------------|
| Tiger Nixon | System Architect | Edinburgh     |
| Ashton Cox  | Technical Author | San Francisco |
|-------------+------------------+---------------|
| Name        | Position         | Office        |

     =====>

<table id="example" class="cell-border hover compact" width="100%">

<thead>
     <tr>
       <th>Name</th>
       <th>Position</th>
       <th>Office</th>
     </tr>
   </thead>

   <tbody>
     <tr>
       <td>Tiger Nixon</td>
       <td>System Architect</td>
       <td>Edinburgh</td>
     </tr>
     <tr>
       <td>Ashton Cox</td>
       <td>Technical Author</td>
       <td>San Francisco</td>
     </tr>
   </tbody>

   <tfoot>
     <tr>
       <th>Name</th>
       <th>Position</th>
       <th>Office</th>
     </tr>
   </tfoot>

</table>

Thx again ... Volker

The Org mode HTML exporter does not seem to provide any facility for
using table footers.  You can use the export-filter mechanism of Org
mode to add the footer, but in this case it is simpler to use the
columns.footer option of DataTables, as in the following sample.

#+title: Org Tables to DataTables
#+html_doctype: html5
#+html_head: <script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
#+html_head: <script src="https://cdn.datatables.net/2.1.8/js/dataTables.min.js"></script>
#+html_head: <link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/2.1.8/css/dataTables.dataTables.min.css" />
#+html_head:<script>$(document).ready(function () {$('#example').DataTable({columns: [{footer: 'Name'}, {footer: 'Position'}, {footer: 'Office'}]});});</script>
#+html_head: <script>$(document).ready(function () {$('#another-example').DataTable({lengthMenu: [3, {label: 'All', value: -1}]});});</script>

This is an example table.

#+attr_html: :id example :class cell-border hover compact :width 100%
| Name        | Position         | Office        |
|-------------+------------------+---------------|
| Tiger Nixon | System Architect | Edinburgh     |
| Ashton Cox  | Technical Author | San Francisco |

------------------------------------------------------------

This is another example table.

#+attr_html: :id another-example :class display
| Author            | Title                   | Shelf |
|-------------------+-------------------------+-------|
| Capote, Truman    | In cold blood           | D3B   |
| Chandler, Raymond | The high window         | D3B   |
| Dai, Mamang       | The legends of Pensam   | D3B   |
| Desai, Kiran      | The inheritance of loss | D3B   |
| Farrell, J. G.    | The hill station        | C1B   |

Re: How can I export a table to HTML with header and footers

Hi

The columns.footer option of DataTables works like a charm ... but just
curious how would you do it with the export-filter mechanism of Org
mode... mayb this comes in handy later

Thx for you help

How can I export a table to HTML with header and footers

[Dr. Volker Zell]

... see subject


Result should be like the following to be used with the datatable framwork


<table id="example" class="cell-border hover compact" width="100%">

   <thead>
     <tr>
       <th>Name</th>
       <th>Position</th>
       <th>Office</th>
     </tr>
   </thead>

   <tbody>
     <tr>
       <td>Tiger Nixon</td>
       <td>System Architect</td>
       <td>Edinburgh</td>
     </tr>
     <tr>
       <td>Ashton Cox</td>
       <td>Technical Author</td>
       <td>San Francisco</td>
     </tr>
   </tbody>

   <thead>

AFAIK, exporting tables with specific id attributes is not straightforward,
but you can abuse the class attribute by putting the id in it.  For example,
if you export a file with the following text (C-c C-e h h), the output may be
like what you want.

I think I was wrong about that:it looks like you can inject a specific
id into a table element with attr_html; I must've misunderstood
something I'd read.  So the following should work too, and does not
abuse the class attribute.
