Introduction
HTML Table Extension integrates the original HTML Table Library.
Although it is a extention it generate very simple tables. If there is a need it can become more flexible i think.
It generate full HTML-Table like this:
<table ...> <!-- start the table -->
<thead> <!-- one row for table header -->
<tr>
<th>yada</th>
...
</tr>
</thead>
<tbody>
<tr> <!-- one row for table sub header -->
<th>sub yada</th>
...
</tr>
<td> <!-- the n table rows -->
<th>row1-cell1</th>
...
</td>
...
</tbody>
<tfoot> <!-- one row for table footer -->
<tr>
<td>end of table</td>
...
</tr>
</tfoot>
</table>
Version
0.1 based on CI 1.7.1 Date: May 2009.
Installation
Copy the code below into a file called MY_Table.php and place it in the /application/libraries folder. Like every extention you can activate it through the table class
$this->load->library('table');
or via autoload.php.
Methods
generate (overwritten)
Now it will generate some more:
- <thead>, <tbody> and <tfoot> tags.
- a subheading on top of <tbody>
_compile_template (overwritten)
some minor changes
_default_template (overwritten)
Some more tags due to the new sections. See end of listing.
set_footing (new)
To set the footing. Works exactly like “set_heading”.
- set_subheading (new)
To set the subheading. Works exactly like “set_heading”.
