Add this as a panel (above the panel with the table)
<panel depends="$alwaysHideCSSPanel$">
<html>
<style>
#table_id td:nth-child(2) {
color: blue !important;
text-decoration: underline !important;
text-decoration-color: blue !important;
}
</style>
</html>
</panel>
This assume you have an id for your table panel of "table_id" and you want the second column changed. Modify values accordingly. Note indexing in this instance starts at 1.
