android - How to arrange buttons with different text-sizes in a TableView so they are not displaced? -

I will just write an RPN calculator app for learning. Buttons are arranged in a table layout. Arithmetic buttons use a larger font size because the symbols are otherwise very small. It produced a little displaced button, but these are all of the same size. It works if all buttons use the same font size.

How can I stop it?

Thank you!

Update: I also tried: Android: Layout_central but no effect
