Please expand on your usecase. If you don't have the field listed in the table, it isn't available to click on for drilldown anyway. Or are you trying to pass on a value from a field which isn't displayed? If so, and the column is always in the same place, for example first, you could use CSS to hide the column <row>
<panel depends="$STYLES$">
<html>
<style>
#hiddencolumns table td:nth-child(1),
#hiddencolumns table th:nth-child(1) {
display: none !important;
}
</style>
</html>
</panel>
<panel>
<input type="dropdown" token="cols" searchWhenChanged="true">
<label>Show Details</label>
<choice value="_time">Just Time</choice>
<choice value="_time,_raw">Time and Raw</choice>
<default>_time,_raw</default>
<initialValue>_time,_raw</initialValue>
</input>
<table id="hiddencolumns">
<title>Show only . [$cols$] - $changed$</title>
<search base="base">
<query>| eval run_on_change = "$cols$ - ".(random()%10)
| table run_on_change $cols$</query>
</search>
<option name="refresh.display">progressbar</option>
<drilldown>
<set token="changed">$row.run_on_change$</set>
</drilldown>
</table>
</panel>
</row>
