Power Query Dynamically Append from Table of Tables

[robarivas]

I have a table (named "TableJoe") of tables  (single column, each row is a full table) in Power Query. I want to append all of these tables together. However the number of tables (i.e., "rows") can vary from time to time. How do I write the "M" code to dynamically append these tables when I don't know exactly how many tables there will be?

(I can't just expand the tables because the header names are not the same within each table. So once I append the table I just unpivot to collapse the excessive columns I get after appending)

Here is the static code (that I want to make dynamic):

AppendedQuery = Table.Combine({TableJoe{0}[SingleColumnName], TableJoe{1}[SingleColumnName], TableJoe{2}[SingleColumnName], TableJoe{3}[SingleColumnName], TableJoe{4}[SingleColumnName], TableJoe{5}[SingleColumnName]})

Hi @robarivas,

You can refer to below formula to combine the tables.

Source table.

Combine formula:

CombineTable= Table.Combine(Source[Data])

Result:

Full query:

let
    Source = Excel.Workbook(File.Contents("C:\Users\xxxx\Desktop\test.xlsx"), null, true),
    CombineTable= Table.Combine(Source[Data])
in
    CombineTable
