Hello Mihajlo,

This is considered an issue. This is why I have logged it on our feedback portal. You can track its progress, subscribe to status changes and add your comment to it here. I have updated your Telerik points as well.

Unfortunately due to the nature of the issue, I cannot suggest a workaround for it. What I can suggest is to inherit the RichTextEditorRibbonBar and override the method that shows the table tabs:

class CustomRichTextEditorRibbonBar : RichTextEditorRibbonBar
{
    public CustomRichTextEditorRibbonBar()
    {

    }

    protected override void HandleTableStylePropertiesOnCurrentEditingStyleChanged()
    {
        Paragraph p = this.GetCurrentParagraph();

        if (p == null)
        {
            return;
        }
        TableCell cell = p.Parent as TableCell;
        var isInRange = this.associatedRichTextEditor.Document.GetContainingAnnotationRanges<ReadOnlyRangeStart>(p.Inlines.First);
        if (isInRange.Any())
        {
            return;
        }


        base.HandleTableStylePropertiesOnCurrentEditingStyleChanged();
    }
}

Let me know if you have any other questions.

Method HandleTableStylePropertiesOnCurrentEditingStyleChanged does two things. It shows the two tabs when caret moves inside the table, and it hides the tabs when caret moves outside. If I have both a protected and an unprotected table and a caret moves from unprotected to protected then the only way to hide the tabs is to do it myself, copying the code from the last else-if part of HandleTableStylePropertiesOnCurrentEditingStyleChanged method.

This brings me to a spotted bug. The mentioned else-if part is "else if (this.tabTableStyle.IsSelected || this.tabTableLayout.IsSelected)". So, Imagine we have a table in a regular rich text editor. Move caret in table and two tabs show up, and the first is selected. Now select some other tab, like Home, and move caret outside the table. Two tabs will remain, which is an error. Instead of IsSelected I think the check should be "Visibility = ElementVisibility.Visible".
