I been reading various document online from CPAN, tablematrix, table configure and cget. I have tried the followings and could not make them work.

#    $info = $table->cget(-bg, "1,1");  #for row,col=1,1
#    $info = $table->cget(-tag, "1,1");
#    $info = $table->cget(-celltag, "1,1");
#    $table->{"row,col"}->cget("tag");
