Selecting columns by column number

Hi,

I am trying to grab columns by column number in hopes of parameterizing the column selection.

I want to be able to dynamically grab values from different columns depending on what the user has selected.

I currently have 2 tables, table1 has 10 rows each representing a possible column that could be individually selected from table2 which has 10k rows and 10 columns.

The problem I want to solve is, if row 1 in table1 has been selected, I would like to perform a lookup from column1 in table2.

row 2 table 1 > column 2 table2

row 3 table1 > column 3 table2

so on and so forth

I would not need to return the entire column just a row specified by filter clicking with the corresponding required column.

Essentially i would like to do a dynamic vlookup in powerbi. 

Does anyone know how this can be done? 

Thanks in Advance,
