This can be supported since the exceljs/exceljs supports rich text inside a cell. However, the CSS styles of the text need to be parsed and converted into a very specific format. Refer this from exceljs/exceljs.
I'm currently not planning to support rich texts inside cells. But, anyone interested in contributing can submit a pull request for this feature.
