What is the best approach to sort a 10 column data table by its column headings. The column headings would also be shown in a separate dropdown list, once the column heading name is selected with the dropdown list I would like the data table to sort on that column automatically. Preferably do it without VB, this may eventually run on a Mac, I'm told VB won't run on a Mac. But would use VB if necessary, since Windows is the main platform.
