{ ADDRESS(row, column, [ref_type], [ref_style], [sheet_name] )
Returns a text representation of a cell address.
"row" and "col": row and column indices, 1-based.
"ref_type" is the type of reference to use: 1=absolute, 2=rel col, abs row,
3= abs col, rel row, 4=relative; if omitted, 1 (absolute) is assumed.
"ref_style" if true (default) means: address in A1 dialect, otherwise in R1C1.
"sheet_name": name of the worksheet. Note, when sheet_name is used the
address is presented in Excel dialects only. }
