User right mouse clicks on a data grid with Date format in Toad 9.7.X. The user does a right mouse click, Save As, and saves the data as an Excel file with the option "include cell border." After the export is complete, the user opens the Excel file and finds that borders were drawn except around the columns with date data.
This issue has been reported to the development team and is waiting for fix in a future release of Toad for Oracle.
Please open the file in Excel, select the date column, and draw the border in Excel.
