Hi Mar Ria,
When exporting the Smart.Grid the only styles that are included are those defined in the dataExport.style property of the element. DataExport is a property of the Grid that allows to configure the exporting of the element. You can read more about it here. If no styles are defined, the Grid applies it’s default. You can read more about the DataExporterhere.
