Delete a selected row in a QTableWidget

I have the following problem: I try to delete a selected row of a TableWidget but it does not work. This is the function I occupy:

self.check.clicked.connect(lambda:self.tabla.selectedItems().clear())

And this is the complete code:

from PyQt5.QtWidgets import *

from PyQt5 import uic 




class Principal(QMainWindow):
    def __init__(self):
        QMainWindow.__init__(self)
        uic.loadUi("columna.ui",self)

        self.tabla.insertRow(self.tabla.rowCount())
        self.tabla.setItem(self.tabla.rowCount()-1,2,QTableWidgetItem("sdsd"))
        self.tabla.setItem(self.tabla.rowCount()-1,1,QTableWidgetItem("sdsd"))
        self.tabla.insertRow(self.tabla.rowCount())
        self.tabla.setItem(self.tabla.rowCount()-1,1,QTableWidgetItem("sdsd"))
        self.boton.clicked.connect(lambda:self.tabla.setShowGrid(False)) #Limpiar sin dejar la rejilla en la tabla

        self.check.clicked.connect(lambda:self.tabla.selectedItems().clear()) #Función para eliminar solo una row




app = QApplication([])
p = Principal()
p.show()
app.exec_()
