how do i limit the amount of decimal places shown in a qtablemodel using pyside6 in python

To limit the number of decimal places shown in a QTableModel using PySide6 in Python, you can create a custom QStyledItemDelegate and override its displayText() method.

Here's an example of how you can achieve this:

main.py
from PySide6.QtCore import Qt
from PySide6.QtWidgets import QStyledItemDelegate, QApplication
from PySide6.QtGui import QDoubleValidator
from PySide6.QtCore import QLocale, QLocaleF

class CustomDelegate(QStyledItemDelegate):
    def displayText(self, value, locale):
        decimal_places = 2  # Set the desired number of decimal places
        formatted_value = QLocaleF().toString(value, 'f', decimal_places)
        return formatted_value

# Create a QApplication instance
app = QApplication()

# Create a QTableModel instance
table_model = QTableModel()

# Set the QStyledItemDelegate to the QTableModel
table_model.setItemDelegate(CustomDelegate())

# ... (add data to the QTableModel)

# Show the QTableView
table_view = QTableView()
table_view.setModel(table_model)
table_view.show()

# Run the application event loop
app.exec()

In the example above, we create a custom QStyledItemDelegate called CustomDelegate. In the displayText() method, we set the desired number of decimal places using QLocaleF().toString(), and then return the formatted value.

After creating the QTableModel and adding data to it, we set the CustomDelegate as the item delegate for the QTableModel using setItemDelegate().

Finally, we create a QTableView, set the QTableModel as its model, and show the QTableView.

Remember to adjust the decimal_places variable to the desired number of decimal places you want to display.
