Interesting Attributes

#name

The Name of this Worksheet.

#default_format

The default format used for all cells in this Workhseet that have no format set explicitly or in Row#default_format.

#rows

The Rows in this Worksheet. It is not recommended to Manipulate this Array directly. If you do, call #updated_from with the smallest modified index.

#columns

The Column formatting in this Worksheet. Column instances may appear at more than one position in #columns. If you modify a Column directly, your changes will be reflected in all those positions.

#selected

When a user chooses to print a Workbook, Excel will include all selected Worksheets. If no Worksheet is selected at Workbook#write, then the first Worksheet is selected by default.
