        self.mainw2 = QtGui.QWidget()
        self.mainw2.showFullScreen()
        self.scrollArea_left.setWidget(self.mainw2)

        self.btn1.clicked.connect(self.insert_rows)
        self.table.setItem(0,4,QtGui.QTableWidgetItem(str(" ")))
        self.setCentralWidget(self.scrollArea_left)

        self.table.insertRow(ct-1)
        self.btn = QtGui.QPushButton()
        self.btn.setIcon(QtGui.QIcon("./delete.png"))
        self.btn.setIconSize(QtCore.QSize(30,60))

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    tb = Table_Program()
    tb.show()

一个简单的解决方案是实现一个自定义QStyle，以禁用QTableWidget中的Highlight选项：

from PyQt4 import QtCore, QtGui

class CustomStyle(QtGui.QCommonStyle):
    def drawPrimitive(self, element, option, painter, widget):
        if element == QtGui.QStyle.PE_PanelItemViewItem:
            option.state &= ~QtGui.QStyle.State_Selected
        super(CustomStyle, self).drawPrimitive(element, option, painter, widget)

if __name__ == '__main__':
    import sys
    app = QtGui.QApplication(sys.argv)
    w = QtGui.QTableWidget(5, 4)
    w.setStyle(CustomStyle()) # <--- set style
    w.show()
    sys.exit(app.exec_())

How can i disable the selection highlighted green in table widget using pyqt4
