I don't think you can copy paste from Excel into Pro/TABLE. I'd save out the Excel file as a space delimited text file. Make sure you include an index column as the first column before saving. Then, you can save out your Pro/TABLE file as a .ptb file. Open the .ptb file in a text editor like notepad and copy paste from you Excel outputed text file into the .ptb file. Save it, and then read the file in while in the Pro/TABLE editor for your pattern. I know it's a pain. Hopefully PTC will be improving this in future releases.
