General Registrant List tool Help is here: Registrant List.

You have 2 options for setting up a field to store the table number/name:

1. Create a "table number/name" field in the About You section - How do I create a field to hold my table numbers/names?
2. Create a "table number/name" question in the Questionnaire Wizard - How do I create a question to hold my table numbers/names?

Use the Table Wizard's Registrant List button to bulk edit your registrants into table seats.

Where do I access the Table Wizard?

Scroll down to the registrant data section and set up the Registrant List so that working on it is most convenient for you: move the columns upon which you will be working to the front of the list

1. Move the Group Code column to the front of the list - How do I move a column in the Registrant List?
2. Next, move the first name, last name and the table number/name column to the front of the list - these are the 4 fields you're working on
3. Sort the Group Code column - this will gather all registrants with the same group code and display them together - How do I sort a column in the Registrant List?
4. Select the registrants that you want to sit at the SAME TABLE by clicking the checkboxes in the blue column
5. Click the Bulk Edit button

Select the Assigned to Table Number: question (you created this question for this purpose).

Repeat these steps for another Table code.
