How to use getState in a grid? [ExtJS 4.1]

Question

Here it says that I can get width (of columns I guess) but only thing I can get is the columns IDs.

grid.getState()

Edit: The response of Ext.encode(grid.getState())

{"columns":[{"id":"280"},{"id":"279"}],"sort":{"property":"DEPARTMAN_NO","direction":"ASC","root":"data"}}

Answer 1

If your original column width is not changed getState does not return width info for this column.
