Train of thought:

1. Define delegation for each column:

The first column is a numbered column. Use a read-only delegate to make the cells in this column read-only
The third column is the ID column, which can only input 1-12 numbers. The qlinedit delegation and regular expression are used to restrict the input
In the fourth age column, QSpinBox delegation is used for input restriction, and only numbers between 1 and 100 can be entered
The fifth column is the gender column. The input is limited by QComboBox delegation. The cells in this column can only enter Male or Female
The sixth column is the head image column. Place a head image in the center of the cell of the column

2. Define a proxy class to display the characters in all cells in the middle.

3. Use QSS to make the background color of the table yellow and blue.
