How to append rows from one table to rows of another

[ai5703]

I have 2 tables where I'd like to append/add the rows from one into another table. However One table has a subset of the columns. Any suggestions?

Fror example

Table A: has columns A thru E. The table has 15 rows

Table B: has columns A thru C. It has 10 rows

The resulting table should have 25 rows with no values for the new cells from table B.

Another example as above would be 2 outputs from a joint operation like the Left output and Joined output

use union tool, connect both files to union tool.
