Expand 3 Columns with Tables Simultaneously PowerQuery

[AEAA]

Hi all,

I am fairly new to PowerQuery. I have 3 columns, each one with a Table (all tables have the same structure and number of rows):

When I expand Column 1, every row of the expanded table gets a table for Column 2 and 3, So I get a big number of duplicates.

Is there any way I can expand all three at the same time so I still maintain the same number of rows?

I have tried Add Column -> Custom Function -> =Table.FromColumns({Proficiency,Frequency,Efficiency}) But it does not work as it does not accept Tables as lists. My idea was to merge all three and then expand in one go.

Thank you so much for the help.

like this Add Column -> Custom Function ->

Table.FromColumns(Table.ToColumns([Proficiency]) & Table.ToColumns([Frequency]) & Table.ToColumns([Efficiency]))

It will leave you with generic column headers Column1, Column2 ... in the table in the added column

How to replace the generic with more meaningful headers depends on whether any of the headers are the same in the three starting tables as you cannot have any header repeated in a table.

Hi JGordon11,

Thank you very much for this. It does exactly what I needed.

The syntax needed a "#" before every column, but PQ added that automatically, so it worked fine.

Table.FromColumns(Table.ToColumns(#[Proficiency]) & Table.ToColumns(#[Frequency]) & Table.ToColumns(#[Efficiency]))
