Any way to auto-fill a cell with a default value?

[Garrett]

I've found (thanks Suzanne) that when you hit TAB in a table, it creates a
new row.

Is there any way to have each cell in the new row fill with a default text?
For example, user hits TAB, and the new cell in the 1st column shows "Enter
name here" and the new cell in the 2nd column shows "Enter birthday here".

Unfortunately, no.
