You can save and recall named table settings. TPC keeps a list of settings for each table type (Line, Curve, Lot, Point), allowing you to change an existing table to a saved setting just by recalling that setting in the Table Properties dialog.
If you want to retain table properties, including any column names you have changed, consider adding that table to a drawing template. See Drawing Templates.
Each time you start a drawing with that template, it will include the tables you have saved in it.
Sticky Table Settings
TPC stores the properties you last edited for each table type in the registry. If you insert a table into a drawing, TPC reads the properties for that table type from the registry and displays them in the Table Properties dialog. You can use them as is, or modify them for the table you are inserting.
