Add contents of two tables to create a third table

I have two tables (Table A and Table B), Both tables have exactly the same columns and all columns except one column are decimal numbers. The tables are related via the one non-decimal column called names.

 

I want to add (sum) each column from Table A and Table B together to create a third Table C, with the one non-decimal number column, i.e.

 

Table C[Column 1] = (Table A[Column1] + Table B[Column1]) where Table A [Names] = Table B[Names].

 

Is this possible? if so, how do I do it?

 

Thanks

Phil

Hi @pburness

 

First, create a Merge Query as below.

Then try to add an Append Query as below:

Then Merge the two queries as below and remove Table columns as requested.

Last, Group the new query as below. You may need to do it with M language in Advanced Editor.

Hi @pburness

 

You may try to use Merge Queries in Query Editor as below.

Then expend the table without name column and filter all values without the null values.

Create custom columns to sum the values from 2 table as requested.

Thanks Cherie,

This works, but I was hoping there was a way to automate the task. There are 80 columns in each table, so not a huge burden, but still a bit of a chore...
