IWorksheetManager.GetColumnLettersFromPosition Method
Excel, by default, uses a reference format known as A1. This simply means that columns are referred to using letters and rows using numbers. References contain a combination of both the column letter and row number, thereby designating a unique cell.
Example: 0 returns A, 1 returns B, 25 returns AA. Unlike Excel VBA, we use base 0 because SpreadsheetGear uses base 0.
