Local sorting of downloaded tables

Abstract From the Canadian patent

Sorting of table data is enhanced by providing hidden sort keys associated with table cell data. When table data is displayed the hidden sort keys are not, but they may nevertheless be used as a basis for sorting table information. Thus table data may be presented in a variety of views with alternative arrangements of data based on whether, each column or row of table data is sorted by content or by the hidden sort key or sorted in ascending or descending order. The table may selectively be restored to its original configuration after sorting. Sorting is invoked by interpreting mouse clicks in a header cell of a table column or row.
