Adding richtextfield (custom component) inside a grid

We have a richtextfield as an input and saving the generated (html) text in the db,

basically we want to show the styled text inside a grid but when we tried it, 
this error was encountered

Interface Definition: Expression evaluation error at function a!gridLayout [line 13]: A grid layout component [label=“”] has an invalid value for “rows”. The row layout at index 1 contains a component that is not supported in the grid layout. Received CertifiedSAILExtension

is there any workaround for this?

Help would be much appreciated
Thanks!
