Enhancement Request: Column Color Selection and Automatic Row Summary

[Dzo4e2250]

Description:
I would like to propose the following enhancements to improve the user experience when creating columns and rows in the "tables" extension:

Color Selection for Columns:

When creating columns and selecting the type "selections", in addition to the trash icon for deleting, there should be an option to choose the color. This feature will allow users to assign specific colors to different selections, enhancing visual organization and clarity.
Automatic Row Summary:

When the first column is created, an additional row should be automatically generated below the column.
For Text Values: If the column contains free text, the row should remain empty and not display any summary.
For Numeric Values: If the column contains numeric values, an option should be provided to calculate the sum of the entire row, similar to the SUM function in Excel.
For Selections: If the column contains selections, a simple graphical representation should be displayed. This graph should depict the frequency of each color used in the selections as a horizontal bar chart, providing a quick visual overview of the most commonly used colors.
These enhancements will greatly improve the usability and functionality of the "tables" extension, making it more versatile and user-friendly.
