The class names used in the TreeView component could be more descriptive. The prefix 'debug-' might suggest that these classes are only used for debugging purposes, which is not the case. Please consider renaming them to something more descriptive and without the 'debug-' prefix. For example, 'debug-treetype-button' could be renamed to 'tree-type-selection-button', 'debug-timetravel-panel' to 'time-travel-panel', and so on.

The onError callback in the editorConfig is directly throwing any errors that occur. This can crash the application if an error happens during an editor update. Consider logging the error and displaying a friendly message to the user instead. For example:
onError(error: Error) {
console.error('An error occurred:', error);
// Display user-friendly error message
}

The current implementation of the InsertTable component automatically inserts a table when the component mounts, without any user interaction. This may not be the desired behavior for a rich text editor. Consider modifying the component to insert a table only when triggered by a specific user action, such as clicking an 'Insert Table' button. This would provide better control and user experience.

The $updateToolbar function only updates the toolbar state when there's a range selection. However, it doesn't handle cases where the selection is not a range selection (e.g., when the cursor is at the beginning or end of the text). This can lead to incorrect toolbar states. Consider resetting the formatting states when the selection is not a range selection to ensure the toolbar always reflects the current state accurately.

There was a problem hiding this comment.
The use of the non-null assertion operator (!) in document.getElementById('root')! assumes that an element with id 'root' will always exist in the DOM. This could lead to runtime errors if the element is not present. Consider adding a null check to handle cases where the element might not exist, improving the robustness of the application.

I noticed that the naming convention in the properties of the object is not consistent. Some properties are named using camel case, while others are named using hyphen-separated words. This inconsistency can make the code harder to read and understand. I suggest choosing one naming convention and sticking to it throughout the code. For example, if you choose camel case, 'editor-text-bold' should be renamed to 'editorTextBold'.

It would be helpful to add an inline comment explaining why we're referencing 'vite/client' here. This will make it easier for other developers to understand the purpose of this code.

The toolbar doesn't track or update the current text alignment state. This means that the alignment buttons don't visually indicate which alignment is currently active. Consider adding state variables for text alignment (e.g., isLeftAligned, isCenterAligned, etc.) and update them in the $updateToolbar function. Then, modify the alignment buttons to use these state variables in their className prop to show which alignment is active.

I noticed that this file implements a TreeViewPlugin, which seems unrelated to the TablePlugin example mentioned in the pull request summary. Could you clarify if this plugin is necessary for the TablePlugin example? If not, consider removing it to keep the example focused on the TablePlugin functionality. If it is needed, please add a comment explaining its role in the TablePlugin context.

The .toolbar class sets fixed padding and margin values. Consider using relative units or media queries to ensure the toolbar is responsive on different screen sizes.
