描述

Hi,

I'm having issue with scrollTo. There are a set of columns I would like to see in the view for a particular jump. See plunker http://plnkr.co/edit/YJAu6irPzKgUURzsf1ju?p=preview. For example, for jump to col10, I want to see 10, 11, 12, 13. This works fine when I jump from higher column number like from 28 back to 10. Col 10 got anchor to the left side. However, when I jump from lower column number like from 1, only col 10 comes into the view and the other columns do not come into the view. Also col10 is anchor to the right side.

I think the jump should behave the same (anchor to the left unless not enough column left to anchor to the left) regardless of where user is scrolling from.

研究方向
Investigate the scrollTo function in the ui grid source code, particularly how it determines the anchor side when scrolling left to right vs right to left. The expected behavior is to consistently anchor to the left unless there are not enough columns. Refer to the plunker example for reproduction. Ensure the fix considers the direction of navigation.
