Print data frame as list including row/column name

Hi all,

I have the following problem:
I have a data frame (actually it is a prop.table) which I want to print as a
list, e.g.:
          C1  C2  C3
  R1  0.0  0.0  1.0
  R2  1.0  0.0  0.0
  R3  0.0  0.0  0.0
  R4  0.0  1.0  0.0

should be printed like
C1;R1;0.0
C2;R1;0.0
C3;R1;1.0
C1;R2;1.0
C2;R2;0.0
.....

Is there any existing solution out there or could somebody please give me a
hint on how to solve the problem?

Many thanks in advance,
I. Sugimoto
