Is there any way by which we can display multiple columns after clicking on the tab in salesforce?

Hi saurabh,

Click on the tab(Which should be realted to any of the custom/standard object)

Expand Force.com Quick Access Menu > Edit Columns > Move the needed fields from Available Fields to Selected Fields. > Click on Save > User should be able to see multiple columns.
(OR)
Click on Setup > Create > Objects > Select the corresponding object link > Under Search Layouts section > Click Edit which should be left to Object Tab > Move the needed fields from Available Fields to Selected Fields. > Click on Save > User should be able to see multiple columns.

Thanks.
