title: How to fill QTableWidget from json in Python
body: <p>I'm working on statistical software which takes data from Cloud Firestore database, puts it into <em>QTableWidget</em> and then into chart. I'm able to create offline backup of database (json below). How can I achieve to fill <em>QTableWidget</em> with data from it? </p>
  
  <p>In my table, I've got 4 visible columns - Date, Type, Published, Sent and one hidden - ID (formatted date, e.g. 050719)</p>
  
  <p>This is .json file I get from database </p>
  
  <pre><code>"{\"events\": {\"050719\": {\"Type\": \"Conference\", \"Published\": \"4\", \"Sent\": \"3\", \"Date\": \"05.07.2019\"}, \"050919\": {\"Type\": \"Conference\", \"Published\": \"23\", \"Sent\": \"35\", \"Date\": \"05.09.2019\"}, \"120719\": {\"Type\": \"Conference\", \"Published\": \"3\", \"Sent\": \"4\", \"Date\": \"12.07.2019\"}, \"150719\": {\"Type\": \"Conference\", \"Published\": \"4\", \"Date\": \"15.07.2019\", \"Sent\": \"2\"}}}"
  </code></pre>
