It isn't a UITable, just a UIPanel
My UIPanel (Clipped View)
has a transform of 0,0,0
Cell Width 330
Cell Height 180
UIPanel (Window)
also has a transform of 0,0,0
The Outline has a size of 650, 200 and is positioned up -115 in the Y direction (problem is with X direction though) Box Collider is scale 1,1,0
It positions perfectly on my window size as I can see it with the purple outline, The two colliders at the left and right are positioned either side against the purple box. Box Colliders are both size 200,300, both at transform 0,0,0
The UIPanel (Scroll bar) which I guess has no relevance has nothing strange in it.
Can't see anything strange there at all.
