Hello, I can help you with your question.
First, when you go to paste the cell, select Paste Special, then check the box next to "Paste Link", and select "Microsoft Office Excel Worksheet Object"
Now you have the cell and you can select it. What you want to do to be able to drag it around is to detach it from the text positions.
To do this, right click on the cell you've pasted special as a link, and select "Format Object", click on the "Layout" tab, and you will see some choices for "Wrapping Style". You do not want "In line with text", and of the other four options will let you drag the cell around with the cursor.
Square - text is moved around the cell in a square box.
Tight - smaller border around text than square.
Behind Text - text is not moved, cell will go behind any text present on that area of the page.
In front of text - text stays put as with Behind Text, but cell is drawn over the text.
Let me know if you have any questions about this.
