End-of-Table Dictionary
To help the Table Locator know where a table ends, provide a dictionary that contains a list of possible keywords that mark the end of a table. In a typical invoice, the keywords, "Subtotal," "Merchandise Total" or "Please pay," among others, usually mark the end of the line items. If you provide a keyword dictionary, all potential line items below the best hit of that dictionary are removed before the result is presented to the user.
Use this dictionary in partnership with a beginning-of-table dictionary to further refine your results.
