pyqt tableWIdge某个单元格点击打开QFileDialog

可以使用如下代码实现：

from PyQt5.QtWidgets import QApplication, QFileDialog, QTableWidget, QTableWidgetItem

def open_file_dialog():
    file_names, _ = QFileDialog.getOpenFileNames(None, "Open File", "", "All Files(*);;Text Files(*.txt)")

    if file_names:
        print("Selected Files:", file_names)

table_widget = QTableWidget()
table_widget.setRowCount(2)
table_widget.setColumnCount(2)

item = QTableWidgetItem("Click here to open file dialog")
table_widget.setItem(0, 0, item)

item = QTableWidgetItem("Another cell")
table_widget.setItem(0, 1, item)

item = QTableWidgetItem("Yet another cell")
table_widget.setItem(1, 0, item)

item = QTableWidgetItem("Final cell")
table_widget.setItem(1, 1, item)

table_widget.cellClicked.connect(lambda row, column: open_file_dialog() if row == 0 and column == 0 else None)
