Add Row Automatically

MIT App Inventor Help
1

I am trying to automatically add a row on a table (first column is a DatePicker) (second column is an amount) (third row is a arithmetic calculation of profit/loss). I want a new row every time I insert an amount in the second column and keeping the format for each row.
How do I do it? I have tried many methods unsuccessfully.
Thank you and blessings.
