15.6.5.4 Including properties of table cells in DITA XML
FrameMaker table cell properties such as shading and border treatments do not translate directly to DITA XML.
For presentational properties, the standard way would be to have XSLT add shading (for example) based on a row count or other content-independent table property.
For semantic properties, you would have to identify in FrameMaker the cells that require treatment. If you use a dedicated FrameMaker format for the content of those cells, you could assign an outputclass value to that format via [StyleCellAttribute]; see §24.4.6 Specifying attributes for table cells. Alternatively, you could use CellOutputclass markers; see §29.2.4 Using attribute markers for HTML or XML.
