Can PQ add Table Columns rather than Sheet Columns? | Power Query | Excel Forum

I made a PQ that tracks my inbound shipments and its product plus several forecasting averages and variances etc.  I am using a series of merges and indexes so that the number of columns in the order section changes based on the number of shipments I have coming in.  Every time my number of shipments increases it adds columns to the Excel sheet and I am wondering if there is a way to have it only increase the number of columns in the Table rather than the sheet.  I have another small table above it that gives order status for each shipment but it  is split by the added shipment columns the PQ is adding.
