2) On Grid I can show automatic num row same in excel will A,B,C,… be header and 1,2,3,… be num row, I can show same that?

>>1) When I use toolbar for Paginal Output, I can set style of toolbar Yes or No ? ( if yes please tell me. )
The styles of toolbar defined in dhtmlxtoolbar.css, you can adjust any necessary style there.
The toolbar object accessible as
    grid.aToolBar
this is instance of dhtmlxToolbar component , so  you can use its API to customize look|behaviors

>>2) On Grid I can show automatic num row same in excel will A,B,C,… be
header and 1,2,3,… be num row, I can show same that?

The count of columns and their labels defined by js command
    grid.setHeader(…
so you can define as many columns as necessary during initialization.
There is a special column type - counter , which can be used to show row numbers
