Answer by warren for Gridlines splunk statistical table

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>
