Template Columns not working

[QualityCode]

Hi,
How can I add new Template columns in my gridpanel ?
I dont have column in my store. I want to add new column to have user input.
I have tried <ext:TemplateColumn> </ext:TemplateColumn> but It does not show up in gridpanel. what should be the dataIndex for the template column ?

Can you please guide.

Thanks
