You already have the entire table, what you send to the ui-table node in the first place? Or is this post editing the data in the table?
I think I can see one way to do it... but there should be other ways I would think, and that is to keep a 'copy' of the table in a flow or global variable, and update that as the table is updated or changed. Then you can use this copy as needed.
The following link gave me the idea that keeping a copy of the table in a flow or global variable would be maintained change by change to the table UI-Table: how to use commands to add / update table content dynamically. But this seems like a lot of work to do this.
