I am using this code to navigate through keyboard in table grid. In my code I have not added this zebra stripes coding. If I add this zebra stripes is overriding my highlighting
Try adding .tablesorter class to your CSS to make the selector more specific (thanks to Kobi for pointing it out) with something like this:
.tablesorter tr.ui-selected td { background: #f77; }
And to add a border something like this should work:
.tablesorter tr.ui-selected { border: 1px solid black; }
or more fancy:
.tablesorter tr.ui-selected { border: 2px dashed red; }
or something like that.
