title: Take in multiple user input values using Qt QTableWidget
body: <p>I'm trying to make a basic UI for taking in user input and displaying the output, using Qt. I just started working with UIs, so this might seem trivial. I have to take in 3 sets of inputs, where each set consists of 90 integer values. Think of each set as a 2d array of 30 by 3. I'm trying to see what the best way to handle this user input would be in Qt. I have used Qt to work on a .ui file and the link below is of a screenshot of what it should look like.</p>

  <p>To be more specific, I have used the QTableWidget to create the table itself. My question now is how do I access user input from each cell of the table and store it into an array for that whole table? </p>
  
  <p>Help will be appreciated.</p>
  
  <p>Thanks!</p>
