method how to fix a height of dhtmlxGrid

I am currently using Daumeditor.
I need to save the contents I have written in the Daumeditor at the DB and to show the data to dhtmlxGrid.
However, when I use
tag and tag, the height is not fixed, so I see the data.
I want to fix the height in such case, but I don’t know how.
I have been searched how to do this in api or forum. But I still did not figure it out.
Please let me know how to fix the height of data in dhtmlGrid.
thank you.

Unfortunately it is not available to fix the height of the grid row. Its height will extend automatically if the it is needed for the content displaying.
