Sigma Grid 2 and CakePHP

[gustavo]

Following the tutorial I have setup a grid in a cakephp application (in early development stage).
Something is wrong between cake.generic.css and gt_grid.css.
Using cake.generic.ccs break the headers of the columns. (In my firefox) The first header is shown but the rest of them are not shown.
If I get rid of the cake.generic.css the headers are ok.
I'm trying the debug process with firebug but can't realize what's wrong.
Firefox 3.5.3 renders only the first header. Internet Explorer (in Firefox) doesn't render any header (just the row).

¿Have anyone experience the same problem?

Kind regards
Gustavo

add the following lines to end of gt-grid.css
.gt-grid table {   background:auto;   border:0;   clear:none;   margin-bottom:0;   width:auto; }
