title: Stack 2 QTableWidgets
body: <p>I'm currently doing a map editor for a game I created, and I have a tiny problem with Qt. It's the first time I use it, but I love the challenge and I thought it would be a great experience.</p>
  
  <p>I'm currently building my interface using Qt Designer and I'm stuck on the map part. Indeed, my map is composed of 2 layers : The terrain, and the units/obstacles/vegetation. </p>
  
  <p>I'm using a QTableWidget to contain the terrain information, but now I would like to stack another QTableWidget <strong>above</strong> it, with the exact same size, so I can place my units, etc. However, I didn't find how to achieve this on Qt Designer. As soon as I create a new QTableWidget, it goes on the side of the first, not above it.</p>
  
  <p>I thought about using the QStackedWidget, but since it only allows 1 Widget to be visible at a time, it doesn't fit my hope.</p>
  
  <p>If someone has an idea, as tiny as it might be, I would be very thanksful.</p>
  
  <p>Have a nice day everyone ! </p>
  
  <p>EDIT : By above, I don't mean aside... I know it's kinda hard to explain. If we consider that the Axis on which we look our screen is Z, I would like both tables to be : 
  - Equivalent on the X Axis (same number of columns)
  - Equivalent on the Y Axis (same number of row)
  - Different on the Z Axis (one table is "deeper")</p>
