I have a small issue when using TabPanel. My application uses a css layout with the following code.
td, th {
padding-left: 5px;
padding-right: 5px;
padding-top: 1px;
padding-bottom: 1px;
}
Everything that uses table layout, but not only tabPanel will look weird.
In general, you can define all possible css classes to return tabPanel back to the normal shape, but is really better do not use such power definition how you have for th, td.
