  5. Press OK. This creates a new data block in the Data Worksheet.

  6. Optional: Right-click on the data block, and select ‘Properties’ from the context menu. Note: You can also access menu options from the ‘More’ button (menu horizontal) in the mini-toolbar. This opens the ‘Table Properties’ panel. In the ‘Name’ field, enter a name for the data block, and press ‘OK’. (See Modify a Column for information about how to rename columns.
