Removing arrow heads in Table borders

[Yolstar]

I seem to be having a problem with my table in PowerPoint inserting an arrow head on the internal borders. When I tab through the cells to create a new row, the line has an arrow head pointing off to the far right side. Hope that made some sense?!!

I can't seem to find anywhere to remove them. Please help... I'm being driven to gnawing my dogs ears off in frustration. Please help me before there is nothing left of my dog!!!

Anything to save your dog's ears!

Try this

Insert a table and Ungroup (say yes to the pop up)
Select a line and fix the arrow heads
With the line still selected right click and choose default for new shapes or similar.

Try a new table, fixed??

Worked for me thanks.

No problem (it's not an obvious method!)
