我有两个 QTableview 小部件，第一个 QtableView 小部件有 26 行和 4 列，第四列只能编辑和和，第二个 Qtableview 小部件有 1 行和 26 列，如果我在第 4 列的第一个 Qtablview 中更改背景颜色会改变，并且在第二个 Qtableview 背景颜色会改变。
在详细信息中，第一个 Qtableview 小部件有 26 行和 4 列，第 4 个只能编辑，第二个 QTableview 小部件有 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 然后单元格颜色将发生变化，然后在第二个 QTableview 背景颜色中的单元格索引 (0,10) 将发生变化。
你必须检测到第二个QTableView对应item的变化，得到那个item的行才能设置第一个QTableView对应item的背景色。
