Assigns columns to be used for 'details' view. TIP: You can reassign columns on the fly without having to repopulate the control. For instance, you can use SetItemText() to add four subitems to an item, but only assign four columns (remember: 1 item + 4 subitems = 5 columns,) thus giving you a hidden column that you can display later by assigning five columns.

	SalArray<SalString> saTitles,
	SalArray<SalNumber> naAlignments,
	SalArray<SalNumber> naWidths,
	SalNumber nNumColumns
