How do i automatically get a column of a table filled up after having other values

Thank you so much Paul, would i be able to copy this table directly into another document and it'll work just fine? Or would i have to do what you did onto that document.
If its cool with you, may i have the code or steps that you went through to complete the table for future reference? Thank you so much for your time
