Suggestions: Support for Excel, enhanced table editing, and event handling

[hydrawork]

Should we consider expanding the scope of this plugin's applications, not limiting it to just CSV file editing?

We could explore adding simple editing capabilities for Excel data files (primarily data without formulas or formatting, which can be easily converted using tools like Pandoc).

Another consideration is the integration of embedded table functionality within Markdown (the current MD table editing plugin is not entirely satisfactory).

Additionally, as mentioned in the previous issue, column operations such as jumping, inserting, and deleting would be significantly enhanced if filtering and sorting features were added.

Furthermore, it would be beneficial to provide row, column, and cell change events, which would facilitate the extension of this plugin for other applications, such as database management tools.

There are quite a few requests here, so please take them into consideration at your discretion.

Thank you for your detailed suggestions and feedback! Below are my thoughts on the points you've raised:

1. Support for Excel data files
   This plugin aims to provide a simple way to edit and manipulate CSV (or similar file types) using virtual text. Pre-processing and post-processing of files, such as format conversion, are not planned at this time, as they introduce additional complexity.

2. Enhanced Markdown table editing
   The focus of this plugin is on operations specific to the CSV format, so this would fall outside the current scope of the project.

3. Enhanced column operations
   This is something I would like to implement in the future! However, it might take some time to achieve.

4. Row, column, and cell change events
   This is an interesting idea that I hadn’t considered. I will look into it, but I anticipate that implementing the necessary diff detection logic could be quite complex, so the priority for this feature might be lower.

Thank you for your thoughtful suggestions! I will add them to the README as part of the project's roadmap.
