Pyside6

[Larz60+]

I wrote some early Qt code using the designer, and have used tkinter and wxpython almost exclusively since.
I am now in early learning of QT using Pyside6, (finally working on an application where GUI will be exclusively QT).
I'm trying to place a QTableWidget on top of a QMainWindow, and am doing something wrong, but not sure what.
Could use some help.

here's the code I attempted to write:

import sys
from PySide6.QtWidgets import (QApplication, QMainWindow,
        QWidget, QTableWidget, QTableWidgetItem)
from PySide6.QtGui import QPalette, QColor


class MainWindow(QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()

        self.setWindowTitle("Table Widget")


class Table(QTableWidget):
    def __init__(self, parent=None):
        super(Table, self).__init__(parent)

        self.colors = [("Red", "#FF0000"),
                ("Green", "#00FF00"),
                ("Blue", "#0000FF"),
                ("Black", "#000000"),
                ("White", "#FFFFFF"),
                ("Electric Green", "#41CD52"),
                ("Dark Blue", "#222840"),
                ("Yellow", "#F9E56d")]

        self.table = QTableWidget()

    def get_rgb_from_hex(self, code):
        code_hex = code.replace("#", "")
        rgb = tuple(int(code_hex[i:i+2], 16) for i in (0, 2, 4))
        return QColor.fromRgb(rgb[0], rgb[1], rgb[2])

    def define_table(self):
        self.table.setRowCount(len(self.colors))
        self.table.setColumnCount(len(self.colors[0]) + 1)
        self.table.setHorizontalHeaderLabels(["Name", "Hex Code", "Color"])

        for i, (name, code) in enumerate(self.colors):
            item_name = QTableWidgetItem(name)
            item_code = QTableWidgetItem(code)
            item_color = QTableWidgetItem()
            item_color.setBackground(self.get_rgb_from_hex(code))
            self.table.setItem(i, 0, item_name)
            self.table.setItem(i, 1, item_code)
            self.table.setItem(i, 2, item_color)


def main():
    app = QApplication(sys.argv)

    window = MainWindow()
    table = Table(parent = window)
    table.define_table()
    # window.show()
    table.show()
    window.show()
    app.exec()


if __name__ == '__main__':
    main()
