adding context menu to a table control

Hi,

i have a screen with table control. i have to select a column on the table control and i have to copy the contents on that column and i have to paste them on a

excel sheet.

[for this i have to add a context menu with copy text option.( This is my opinion )].

I dont know how to add that context menu to an ordinary table control. please help on this for copying contents of the field to the clipboard.?
