Trying to write If statement for table behavior

Scenario
If table on page has data then click call to action
If table on page does not have data refresh the page

I attempted to do the following- Did not work
Command: if
Target: I used the select to highlight this Nothing found to display. but couldn’t add an operator to finish the statement.

When my table has data it has a class=“odd” value
When my table does not have data it has a class value=“empty”
