this syntax requires column names to be the same.

That is incorrect.  There is no requirement that the column names need to be the same.  Table.Combine can append tables even if they have no columns in common.

You can impose the column names of one table onto the other table (for example via Table.RenameColumns), and then append them.

    Hi Ibendlin,  sorry but I was reading and trying and the columns has to have the same name.

    I know I can rename the columns but I have 50 tables with 48 columns each one, It is possible but it seems a bit inefficient  and difficult to maintain.

     

    If you have a syntaxis to combine two tables with same structure but different columns name please share it!!
