Indeed the reported behavior is an issue and I have logged it in our feedback portal
, here: FIX. RadRichTextEditor - table borders with different widths are not painted consistently
. I have also updated your Telerik points
for the report. Additionally, you can subscribe to the item and be updated when its status changes. Due to the nature and complexity of the issue, I cannot suggest a suitable workaround.
Let me know if you have other questions.
