PySide2.QtWidgets.QTableWidget: why it's impossible to set column width less than 35 and row height less than 21?

Zunder

I am using code like following, trying to create a table of square cells. But when I try to use 5 (or even10) as cell size, I get table with rectangular cells with size of 35x21?

def create_square_table(self, cell_size=5, cell_number=5):
      square_table = QtWidgets.QTableWidget()
      square_table.verticalHeader().setDefaultSectionSize(cell_size)
      square_table.horizontalHeader().setDefaultSectionSize(cell_size)
      square_table.setColumnCount(cell_number)
      square_table.setRowCount(cell_number)
      square_table.horizontalHeader().hide()
      square_table.verticalHeader().hide()
      square_table.setHorizontalScrollBarPolicy(QtCore.Qt.ScrollBarAlwaysOff)
      square_table.setVerticalScrollBarPolicy(QtCore.Qt.ScrollBarAlwaysOff)
      square_table.setAlternatingRowColors(True)
      square_table.setEnabled(False)

      print('Column width:', square_table.columnWidth(0))
      print('Row height:', square_table.rowHeight(0))
      return square_table
table = self.create_square_table()

The text printed in console is:

Column width: 35
Row height: 21

Hi and welcome to devnet,

What are you going to show in these little squares ?

@SGaist , Hi! And thank you!
I want to print single digits (from 1 to 6) there.
Frankly speaking, I want to visualize the process of solving one kata from codewars.

And how many do you want to show in total ?

I have the feeling that you might not be using the right tool (I may be wrong though).

I want to show 6 by 6 tables, that will be CellWidgets of an outer table of 6 by 6. So small square cells are better for this task, because the whole table can be square and smaller than table that is made of rectanguler cells 35x21.

I was thinking about using gridLayot instead of tableWidgets. But in my opinion it will be more difficult to manage such an interface. Am I right?

This is how my intermediate result with 35x21 inner cells looks like:

I wonder if the Pixelator example would be a good starting point for you.
