Define the tables within the Google Spreadsheet.
This property is used to define the ranges within a sheet that will appear as tables. The value is a comma-separated list of name-value pairs in the form [Table Name]=[Spreadsheet Name]_[Sheet Name]![Range] or [Table Name]=[Spreadsheet Name]_[Sheet Name]![Range]. Table Name is the name of the table you want to use for the data and will be used when issuing queries. Sheet Name is the name of the sheet within the Google Spreadsheet and Range is the range of cells that contain the data for the table.
Here is an example DefineTables value: DefineTables="Table1=Spreadsheet1_Sheet1!A1:N25,Table2=Spreadsheet1_Sheet2!C3:M53,Table4=xIsPcLs2-bF3AavQcSLCfzs3kGc_Sheet4!C20:N60".
