Creating replicate rows in KNIME

Hello

I am after a solution to create replicate rows in KNIME where the number of replicate rows is given by a column value. Suppose I have the following table:

col1  col2  col3  col4

A      B       C      3

...

I would like to replicate each row x times according to col4 (in this case 3 times). So the resulting table would like like this:

col1   col2   col3  col4

A       B        C       1

A       B        C       1

A       B        C       1

...

Any help would be much appreciated

Thanks, K
