[h3]Introduction[/h3] 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: [code]

<!-- start the table --> <!-- one row for table header --> ... <!-- one row for table sub header --> ... ... ... <!-- one row for table footer --> ...
yada
sub yada
<!-- the n table rows --> row1-cell1
end of table
[/code]

[h3]Version[/h3] [b]0.1[/b] based on CI 1.7.1 Date: May 2009.

[h3]Installation[/h3] Copy the code below into a file called [b]MY_Table.php[/b] and place it in the [b]/application/libraries[/b] folder. Like every extention you can activate it through the table class [code]$this->load->library('table');[/code] or via autoload.php.

[h3]Methods[/h3]

[h4]generate (overwritten)[/h4] Now it will generate some more:

  • , and tags.
  • a subheading on top of

    [h4]_compile_template (overwritten)[/h4] some minor changes

    [h4]_default_template (overwritten)[/h4] Some more tags due to the new sections. See end of listing.

    [h4]set_footing (new)[/h4] To set the footing. Works exactly like "set_heading".

    [h4]- set_subheading (new)[/h4] To set the subheading. Works exactly like "set_heading".
