[PyQt] [Solved]Help displaying a table with QSqlTableModel

[Extra]

Never mind I got it.

I just commented out:

 # self.CategoryTableView = QtWidgets.QTableView(self.centralwidget)
        # self.CategoryTableView.setStyleSheet("background-color: rgb(255, 255, 255);")
        # self.CategoryTableView.setObjectName("CategoryTableView")
        # self.formLayout.setWidget(13, QtWidgets.QFormLayout.LabelRole, self.CategoryTableView)

And moved the table to the coordinates:

self.formLayout.setWidget(14,0, self.CategoryTableView)
