PR Summary

• Addition of 'yiisoft/data' Dependency
  The project's dependency list was updated to include yiisoft/data. This new software package is now an integral part of our project, and the version we are using is the development version, dubbed as version 1.0.

• Updates in user/index.php

  • Usage of User Class: The standard class for managing users has been incorporated in our project.
  • Column Creation Method Change: The previous method for creating columns has been replaced with a new method, making our code cleaner and efficient.
  • Refactoring Callback Functions: The functions that are called back for processing content have been renamed with clear type hinting, which means they are now easier to understand.
  • Column Header Display: The way we construct columns has been updated to include a header argument, which will help us in displaying information in structured, descriptive columns.
