How to import a Microsoft Excel table into a drawing.

See Resolution Below.
Resolution
-----------------
To Place a previously created Microsoft Excel worksheet on a drawing, use #Insert, #Object, #Create new from file and browse to the file name of the worksheet.
The text will display as the color used in the worksheet, so if the text color in Microsoft Excel is black, the text will blend into the background of the drawing. Change the text color either through Microsoft Excel or by modifying the text style through Pro/ENGINEER.
Double clicking on the worksheet while in the drawing will start up Microsoft Excel and changes can be made to the worksheet.
