[gesp89]

Hello,

I'm having a problem with a file in excel. When i copy an excel table to word my computer goes super slowly. I have find the reason but i can't find the solution for this.
So it creates a lot of line shapes in the middle as you can see in the picture attached. If i drag i see that i have a lot of shapes are still there.

Can someone help me here?

I found the solution, i just had to select objects by clicking "Find and Select-Select objects" and delete them. That's why, for some reason i have my table slow.

Thank you anyway
