title: This is a GUI on QT C++, I generally want to do visual representation from Infix to postfix conversion
body: <p>I generally want to add the entered text in the specific cells of the table..... as you know visual representation of infix to postfix takes some input then step by step converting it into postfix.
  I want to hide the whole table then for each click on button I want to show 1 row.
  I'm unable to link texteditContainer to the table.
  how to do conversion?</p>
