well…
- keep your column contents short and to the point
- try making tables dynamically with dataview, on demand (there if you are in source mode, tables are not even generated which is good if you are navigating a note to edit other parts)
- with dataview you can filter for specific properties making the table possibly smaller
- you can – thru dataview again or even without it – make use of the db folder and projects plugins where you can filter or manipulate table contents further
