Hello Alexandre,
you can explicitly specify the necessary order of columns explicitly using the “Reorder columns” action. The first rule must specify the leftmost column. The rest of rules should use the “After column” positioning. However for many columns creating all the rules can be tedious.
Alternatively, you can use the feature of the “Append” action that the order of columns is always defined by the table to which another table is appended.
See the example below that demonstrates the both variants to specify a column order explicitly.
