You can add an application tag to a row or column. If you prefer, you can associate data with any cell in the spreadsheet, or the cells in a column, a row, or the entire spreadsheet. The string data can be used to interact with a row or column, or to provide information to the application you create. The row data (column data), or row tag (column tag), is similar to item data you can provide for the spreadsheet or cells.
Since the row tag (column tag) is declared as an object, it is very flexible; it can be a number, a boolean, a string, or an instance of a class.
For more information on tags, refer to the Tag property in the Row class or Column class and the GetCellFromTag method in the SheetView class.
