I want to use split button in grid cell. I define renderer for cell, but I can't put extjs component in grid cell. Can anyone help?

You can't put components in grid cells, which is an odd limitation.
Check out http://skirtlesden.com/ux/component-column , he has built an extension that overcomes this.
