datagrid| Printing can achieve the printing function as shown above.
• All fonts, margins, header height, row height, can be customized.
• Supports automatic calculation of the number of rows per page and fixed rows per page.
• Support footer display pages.
Because of their own use and I am lazy, so the attributes are set to public, the time to assign value carefully.
