AlloyEdior allows running the commands to manipulate the table content only when active element is td or th. So there is no need to have "insert rows"/"insert columns" buttons in "table" and "table row" toolbars.

Steps to reproduce:

1. Insert a table using the Online Editor
2. Using elements path click on "table" or "tr"
3. Try to insert new rows/cells

Current results:
No new rows/cells are inserted

Expected result:
New rows/cells will be inserted

This happens because of https://github.com/liferay/alloy-editor/blob/master/src/plugins/tabletools.js#L821

I think it would be good if the tableCell and tableHeader would still extend the EzConfigTableBase.
You can do something like this to override the buttons array:

constructor(config) {
    super(config);
    
    const editAttributesButton = config.attributes[this.name] || config.classes[this.name] ? `${this.name}edit` : '';

    this.buttons = [
        'ezmoveup',
        'ezmovedown',
        editAttributesButton,
        'tableHeading',
        'ezembedinline',
        'ezanchor',
        'eztablerow',
        'eztablecolumn',
        'eztablecell',
        'eztableremove',
        ...config.extraButtons[this.name],
      ];
}

@dew326 can you please check 3b940b7? Table cells extends basic table config, and table header extends table cell. Please let me know your thoughts on this one.

I like this approach.
