When using the sScrollX, sScrollXInner and/or sScrollY to achieve a fixed header table with its inner content scroll
I had this very same problem and seen a lot of complicated answers that never seemed to work. I did solve it by simply overriding the CSS (site.css) on the following and it fixed it in Chrome, IE, and Firefox:
table.display td {
padding: 0px 5px;
}
/* this is needed for IE and Firefox if using horizontal scroll*/
table{
max-width: none;
min-height: 0%;
}
This overrides the CSS in datatable.jui.css
