To make it easier to edit text in tables without disturbing layout, mark-up the tabular region with an Iceni Table Box. For maximum effect, it is best to do the marking-up of tables before you begin your first edit on the page.
Infix Pro PDF Editor will try to make each cell into a separate paragraph. Though this will assist with editing, it is not a full table editor but just a collection of text boxes. 

Notes
  • If you need to add or move rows, use the Object tool (Object tool button) to select and move and duplicate columns or rows of text boxes and lines.
