here | cl0 | cl1 | cl2
-----------------------
  rl0 | c00 | c01 | c02
-----------------------
  rl1 | c10 | c11 | c12
-----------------------
  rl2 | c20 | c21 | c22

I have this kind of grid where clx are collumn labels 
(SetColLabelValue), rlx are row labels (SetRowLabelValue) and cxx cells 
for row and collumn (SetCellValue).
But how can I go to the cell with the value "here" and set a text?
