It's pretty easy to manipulate the columns of the table into the bones of the Match() codes that you need by concatenating the two columns along with some double quotes (") and commas (,) with a formula like this:
"\!"" || :a || "\!" , \!"" || :b || "\!", "
Then, just highlight the new column with the concatenated values in the data table and choose Edit->Copy to get those values onto the clipboard.
Now, you can open your new Formula Editor where you want the Match(), add the Match function, set the match column appropriately and then double click on the Match function to get the JSL editor for it. Paste over the two Empty() functions with your copied values. Be sure to remove the trailing comma (,).
