我試圖開發一個GUI來管理科學結果。爲此，我想介紹兩個數據集的結果。用戶將有一個可視化的reprentation來幫助他比較兩個QTableView中的結果。從兩個QTableView鏈接行以進行視覺比較
圖片：比較器的結果，
我想從兩個錶鏈接線，所以他們始終存在面對面。 當在一張表中改變命令時，其他命令將按照其順序依次相連。 最後，我想添加空行面到另一個表中沒有相對行的行。
我被認爲使用QSortFilterProxyModel，但我不知道如何使用它。
編輯 我的問題似乎並不清楚。我在這裏公式化。我發現自己是一個解決方案，所以這裏是我正在尋找的一個例子。
在此示例行上，我根據名稱（bla，bli blo，blu）鏈接線。我們在同一行看到，表格呈現結果「bla」和「bli」的面對面線，因爲左側模型和右側都有。 右表中沒有「藍光」。所以我添加一個空行。 同樣在左邊的表中使用「blo」
在此示例中，項目按右表的「配置」進行排序。左表必須遵循右表選擇的順序。
這裏我沒有解決方案代碼
