我想知道如何在qtablevi中选择行值

Question

我有两张桌子。我想在table1中获取所选的值并将其放入table2。你知道吗

例如，如果选择1，table2 我希望输入第1行的全部值，并将下一行5添加到第5行。 总之，我想让table1在table2中显示选中的行值。你知道吗

我不知道如何加载所选的table1值，但我认为最好使用table2中的self.serch.table.setModel将一个值附加到QStandardItemModel中的def table1_DoubleClicked (self):。我该怎么做？你知道吗

您可以尝试以下操作，它将选定行从一个表复制到另一个表：

def table1_DoubleClicked(self, index):
    rows = []
    row = []

    for column_index in range(self.columncount):
        cell_idx = self.select_table.model().index(index.row(), column_index)
        row.append(self.select_table.model().data(cell_idx))

    rows.append(row)

    search_table_model = QStandardItemModel(len(rows), self.columncount)

    for i in range(len(rows)):
        for j in range(self.columncount):
            search_table_model.setItem(i, j, QStandardItem(rows[i][j]))

    self.serch_table.setModel(search_table_model)
