Custom report - tables and conditional cell formatting

Hi,

Is there a way to use conditional cell formatting whithout knowing the name of Properties ?

For example, considering a table like this :

col1 | colZ | colW | etc...
0.2 | 0.01 | 32 | ..
"NA" | 0.02 | "NA" | ..
... | ... | ... |


Is it possible to change the format (background color for example) of all the "NA" cell and for all the properties ?
I know name of the columns could be retrieve using RPropertyNames, but I didn't find a way to use that for the cell format.

Thanks a lot.

Michael
