From the top of my head you can use one of following two options:
create same headers for each table before concatenation. To do this use Extract Column Header node after each table and define your prefix (default is "Column ")
other option I had on my mind actually won’t work but I’m too lazy to modify my reply now
Hi,
I receive the same type of data from different sources, but they have different column naming (for example one has amount another value,…) and different order.
I use “Insert Column Header” node the first table is the received data , the second table is the dictionary table which is used for replace old column names with new names. If in the future I receive data with new column names I just update the dictionary table.
Use the node in a loop and tables will be concatenated
