SortColAttributes


Unit:SDL_datatable
Class: TNTabEd
Declaration: procedure SortColAttributes (Ascending: boolean; LowCol, LowRow, HighCol, HighRow: integer);

The method SortColAttributes sorts the data contained in the range [LowCol,LowRow] to [HighCol,HighRow], the column names, the column attributes, and the decimal place indicators according to the column attributes. The values outside this range are not affected. The parameter Ascending specifies whether the valus are to be sorted in ascending (TRUE) or descending (FALSE) order.

The sorting is performed by a modified bubble sort (CombSort), which has been reported to be comparable in speed to QuickSort (see also R.Box, S. Lacey, BYTE magazine, April 1991).
