The idea of the script is to automatically extract fields from a table row and use that information to create maps that aid in editing and navigation of the table. The user first marks a table row as the table heading. The line does not literally have to be the table heading, but it should be representative of the typical row of the table in question. The script also has an alignment feature that aligns the fields of the row with that of the heading. Editing a pre-existing table frequently leads to misaligned rows and this feature alleviates the need to manually add/remove padding.
