Export Distribution Model in RapidMiner

Question

I have an example set in rapid miner.It has 2 columns. for Example

colA  colB 
a     1
a     2
b     3
b     2

=====

I have used naive Bayes. It gives probability for each of colB for colA in distribution table. for example, P(2) = .5

I need that distribution table output. 
write model, excel csv, write does not help.

What should I do ? Thanks in advance.

The simplest solution would just mark the table with you mouse (Strg+A works as well) and use copy and paste.

Unfortunately this only works manually, if you have to export the data very often, the next best step would be to write your own operator for it (which is actually quite simple and requires only basic Java skills): http://docs.rapidminer.com/developers/

thanks David, But are you sure it is not possible in rapid miner ? – Sazzad Jan 18 '16 at 09:44
Yes I'm quite sure. Not every result type can be easily exported. – David Jan 18 '16 at 12:10

Yes you can. If you install the Reporting extension from the marketplace (it's free) then you can export the distribution table, plot view or text view.
Here's a sample process.

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="7.0.000">
  <context>
    <input/>
    <output/>
    <macros/>

      </operator>
      <operator activated="true" class="retrieve" compatibility="7.0.000" expanded="true" height="68" name="Golf" width="90" x="112" y="85">
