Function Names
table exploreDescription
This function explores the table for sub-tables. It will scan through the entire table in a reading-style manner (1st row left-to-right, then 2nd row, etc.)
to identify all sub-tables with contents.
Following criteria must be met for the beginning of the sub-table: X adjacent columns in one row must be non-blank.
If number of starting rows is bigger than 1, then in X adjacent columns at least one of the rows must contain contents.
This allows table recognition in case the header consists of multiple rows and has blank items.
The end of the table is recognized by number of adjacent blank rows below the identified table.
