How can I use my google spreadsheet A Row as a primary key?

Hello I am new to Retool and have a question about using Google Spreadsheet.
I imported my spreadsheet and it has index of each column(primary key) on the A row.
After import the sheet, I saw that A row data(which is column index) is in the first row as a data.

I want to make the first row as a primary key.
How can I do that?

I add my first row of my table.

Hey @sig! Welcome to the community! There should be a setting in the table inspector that allows you to select the column that you want to use as the Primary Key.
