Hi @YazanALJ , one of the problems is that having split the table using something like Table Cropper (which can be used to split by column number), it is tricky to concatenate, or “stack” the sub-tables because you need to ensure they each have the same column names. It would be a lot easier and simpler if the Concatenate node could concatenate table columns positionally but unfortunately that option is not there currently. (I live in hope! 
)
As a result you need to do some extra work to fix the column names. I have uploaded a workflow with a variety of possible solutions. There may be other options that I haven’t considered…
