问使用来自不同线程的数据实时更新QTableView的最佳策略

// NOTE:
// In this example I'm assuming that the thread continues to work after
// preparing first batch of data. One thread can prepare multiple batches
// over time. If that's not the case for you then you can probably
// safely ignore mutex stuff and intermediary tmp variables.
