Reason is I have a loan repayment calculator that produces varying number of rows depending on the loan duration. If I want to combine numerous loan schedules with arbitrary length, I would like to merge them in this way

If the multiple tables are coming from imports (e.g. an Excel doc has multiple tabs, one per loan, and you are trying to collect them into a single table – a perfectly good idea), you can use Incremental Imports.
