Hi, i had try using jqgrid for my application.
i discover one thing,
which if the table only display 3 columns, not include checkbox column.
the navigation bar at the bottom will be aligned to left.
i had done quick check, found that the refresh button bar,
the 25px cause the problem.
you may want to investigate more.

when i display 4 columns or more, the navigation bar back to correct location, which is center of the list.

this does not happen to the top navigation bar.

thanks.
