Is there a celltype that only show a button on the right?

hi.
I want set a cell type that only show a combox button on the cell right, when click the button, that I can show a messagebox or a form by myself.
Is that possible?
Thank!

You need to create your own custom excell.
Here you can find a tutorial:
