Hi Solveig!
Select your range of cells to be pasted.
Then press the shortcut CTRL X, your range will be marked up with a walking line around it.
Next: go to your desired table sheet.
Click once to select a cell like A1.
Then press the shortcut CTRL V to insert the content in there.
The best known shorts ever:
CTRL C and CTRL V to copy and paste something.
CTRL X and CTRL V to cut off and then paste something.
Hope that helps. Greets, Eva
