Entity description, <table> crash

I need to display a table of information alongside an entity in an infobox. I thought I could use the <table> tag to do this, but it crashes and says "color required".

I have tried setting the color inside the table tag, but it still crashes for the same reasons. Is this intended?

Sorry for the delay in getting back to you. Can you post a small example that shows the problem? This doesn’t sound like a bug in Cesium but if it is we definitely want to fix it.
