如何在 pyqt4 中删除整行(qtable widget)

Question

当我尝试删除所选行时，出现以下错误：

"TypeError： QAbstractItemModel.removeRow(( 的参数 1 具有无效类型"。

我已经搜索了很多在pyqt的qtablewidget中删除选定行/行的正确方法。但是，我无法删除选定的行。

您能否分享一个示例代码，用于删除pyqt的qtablewidget中的选定行/行？

import sys
from functools import partial
from PyQt4 import QtGui, QtCore

class Example(QtGui.QWidget):
def __init__(self):
super(Example, self).__init__()
self.initUI()
def initUI(self):
self. table = QtGui.QTableWidget(self)
self.table.setGeometry(10,70, 600,300)
self.table.setRowCount(3)
self.table.setColumnCount(6)
self.table.verticalHeader().hide()
self.table.setEditTriggers(QtGui.QAbstractItemView.NoEditTriggers)
fnt = self.table.font()
fnt.setPointSize(11)
self.table.setFont(fnt)
self.table.setHorizontalHeaderLabels(("S.no, Item,Qty,Rate(Rs:),total,"",").split(','))
all_data = [("1", "xxx", 10, 0),
("2", "yyy", 20, 0),
("3", "zzz", 30, 0)]
for r, row_data in enumerate(all_data):
for c, value in zip((0, 1, 3), row_data):
it = QtGui.QTableWidgetItem(str(value))
self.table.setItem(r, c, it)
for r in range(self.table.rowCount()):
spin = QtGui.QSpinBox(minimum=0, maximum=50)
spin.valueChanged.connect(partial(self.calculateSubTotal, r))
self.table.setCellWidget(r, 2, spin)
btn = QtGui.QPushButton(icon=QtGui.QIcon("trash1.png"))
self.table.setCellWidget(r, 5, btn)
# selected = self.table.selectedItems()
# btn.clicked.connect(self.remove)
self.setWindowTitle("table")
self.setGeometry(200, 300, 400, 300)
self.show()
# def remove(self,row):
# self.table.removeRow(self.table.currentRow)    
def calculateSubTotal(self, row, value):
rate = float(self.table.item(row, 3).text())
subtotal = value * rate
item_subtotal = self.table.item(row, 4)
if item_subtotal is None:
item_subtotal = QtGui.QTableWidgetItem()
self.table.setItem(row, 4, item_subtotal)
item_subtotal.setText(str(subtotal))
def main():
app = QtGui.QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_()) 

if __name__ == '__main__':
main()

你的语法几乎是正确的，试着添加括号：

self.table.removeRow(self.table.currentRow())
