Hide Row and Column numbers

Hello Ramarkishna,
Thank you for your question. Please have a look at the following example: https://codepen.io/webdatarocks/pen/XBPOmB. You can try setting showHeaders: false property to hide row and column numbers. When you need to see only used cells you can make the border-color of empty cells transparent.
Please let us know if the suggested approach works fine for you.
Regards,

Wow that was great! 
Is it possible to resize grid to auto fit with data content? means I don’t want to show white space in report.
At the same time can we hide menu_content, menu_open, menu_save icons?

Hello, Rama,
Thanks for your reply.
Currently, the grid is not resized to auto fit with data content. As about the Toolbar icons, we suggest checking out another forum thread. 
Hope it was helpful.
