Menu as default data to a column in datatable

i have a table were data’s come from db i need to add a menu as a last column in every row with edit ,delete etc options

Usually what I do on the table is put the buttons on the toolbar of the table. Disable the buttons when no row selected, and enable it when any row selected. I think this design way better than put the button on each row.

However, it is possible. Please check the similar topic: http://forum.webix.com/discussion/6022/how-to-show-context-menu-on-button

thank you
