Hey @Derek_Rungsea you can do this easily by creating a button that will AddRow() to a new Zapier trigger table. I typically make special Zapier tables with a 
icon.
Set each column in the table to be a field you want to pass to Zapier, so if you want to pass First Name, Last Name and Email Address all of those will be columns in your table AND each of those will be params in your AddRow() formula.
Then head over to Zapier and create a new trigger zap for Coda New Row Added to Table. You will be able to select the First Name, Last Name and Email Address as all column reference points to be used in your Zap.
Its easy to do! Good luck and let me know if you need any more help.
