Adding span to my headers

[joeworkman]

I am building my table from an existing HTML table. In my existing table, I am using spans inside of the table headers for some styling (adding icons). However, when gridjs processes the content for the headers, it's treated as raw text. Is there a way that I can fix this? I thought I would ask here before posting a bug...

Actually I tried this as a workaround. What I was originally hoping was that gridjs would simply use my table as is instead of building a completely new one. It would be nice if that could be an option. Or it could be nice if the classes that are added to the cells would be maintained when the new table is built.

I found the docs on HTML in headers: https://gridjs.io/docs/examples/html-header-cells

However, it does not seem to work when import from an HTML table.
