"chapter" in table

[Alemps Florimond <ntuflorimond@yahoo.com>]

Hello,

In engineering world, there are some tables :
* where columns are defined for the whole table (item #, designation, power, weight, voltage...).
* some lines related to the same topic (Elevator #1, conveyor #2 ...) are grouped.

To achieve ths, there a different options :
1. To repeat the name of the topic on each line
2. To create a new table for each topic

I find those options not really elegant (identical first cells of each row, or management of headers and columns/colspec for each tables).
Instead of :
db.cals.table
ÂÂÂÂ* tgroup
 Â  * colspec
    * thead
    * tbody
    * tfoot
This kind of "schema" could help answer such a requirement :
db.cals.table
 * colspec
 * thead
 * tfoot
 * tgroup
   * thead
   * tbody
   * tfoot
Â
There a is a common header for the whole table, managed like today when published (repeated when changing pages as an example).
A tgroup corresponding to a given topic embed a thead and containing the row of the "title" (with an adequate colspan) enables the reuse of a consistent set of rows.

What do you think ?
