Format Table's First Column to another Table's First Column

[Alyssa_Gono]

I want to copy a table’s first column to a new table’s first column. I want to do it automatically just like below:

First Table First Column
123
321
123
134

The second table must look like below.

Second Table First Column
123
321
123
134

Everytime , I add a row to the first table, it must also a row to the second table. How to do it ? The code below, generates a different result.

[Table A].[First column]

Output :

123, 321, 123, 134
