It is possible to edit any table and its contents using the “Edit” tab on the top bar, but be careful with this, and make a backup copy of the table before editing!The tab “table keywords” on the left side of the table browser will allow you to look at sub-tables by left-clicking and then view the desired sub-table. Another useful feature is to make a 2D plot of the values in two table columns.
