The ptree_create_table() function creates a table object and returns the handle of the table in tbl_hdl.
The ptree_add_row_to_table() function adds a row of properties to the table specified by tbl_hdl. The handles of the properties of the row are specified in the proph array and nprops specifies the number of handles
in the array. The number of columns in the table is determined from the first row added to the table. If extra column values are specified in subsequent rows, they are ignored. The row is appended to the end of the table.
