Select an object to edit its properties.
This object will be drawn immediately below the table's last row — whichever page that turns out to be, whether the table has 1 row or 100.
If a shape is blocking something underneath it, select the shape here or in the Layers list, then send it backward — or just click directly on the item in the Layers list on the left.
Pick each column's field from the dropdown — it lists every field from your TRAN row.
Don't see yours? Choose ✏️ Custom field… to type it, or click "Detect fields from a sample row" below to load fields straight from a real row of your data.
When on, a short table is padded with a blank bordered block down to just above whatever's placed with the "Right after the table ends" role — so a 1-2 item invoice still fills the page instead of leaving a big gap. Pages with enough real rows to fill on their own are unaffected.
