Presuming this is on a Dashboard, you can change the CSS for the element to do what you want.
In a hidden panel on the Dashboard, add some CSS styling – then connect the elements to their respective styles.
For example,
<panel>
<html depends="$hideCSS$">
#chooser .table th{
font-size: 0ps !important;
visibility: hidden !important;
}
#chooser .table td, .table a{
text-align: center !important;
border: 1px solid blue !important;
}
</html>
<table id="chooser">
...
</table>
</panel>
