The purpose is to make an adaptable report that may have mixed columns

##Define a Report class with properties for common columns (title, date, and author) and an array for
dynamic columns.
##The addColumn method allows you to add custom columns to the report.
##The generateReport method constructs the report content by combining common and dynamic columns.
class Report
##Here’s an extended version of the Report class with support for adding and removing columns

To dynamically add or remove columns in the middle of a report, you can enhance the Report class. 
1. Adding Columns:
    Create a method (e.g., addColumn) that allows you to add a new column to the report.
    Specify the position (index) where the column should be inserted.
    Shift existing columns to accommodate the new one.
2. Removing Columns:
    Implement a method (e.g., removeColumn) to remove a column by its name.
    Adjust the remaining columns to fill the gap left by the removed column.
