我有两个QTableview窗口小部件，第一个QtableView窗口小部件具有26行和4列，第四列仅可编辑，并且和，第二个Qtableviw窗口小部件具有1行和26列，如果我在第4列的第一个Qtablview中更改了背景颜色，则在第二个Qtableview中尊重背景颜色会改变。
在详细信息中，第一个Qtableview小部件具有26行和4列，第4个仅可编辑，而第二个QTableview小部件具有1行和26列，如果我在第一个QTableview中的单元格索引（10,3）中填充任何tex，则单元格颜色将改变，然后在第二个QTableview背景颜色中的单元格索引（0,10）中的相应值将更改。
最佳答案
您必须检测第二个QTableView的相应项目的更改，获取该项目的行，以便能够设置第一个QTableView的相应项目的背景色。
