How to prevent joining values in Row Group (column) of Crosstab? - jasper-reports

Question

Is there a way to unmerge cells with the same value in crosstab?
The problem is that same valued cells are getting merged.
I want the value to be repeated and have cell borders. For example, in a row group, if i have 2 columns, col1 with values 'abc' and col2 with values 1,2,3 and if there are 3 rows, the col1 is one big cell with 'abc' printed only once.
This is what I don't want and instead want it to be printed 3 times.
This is presentation I required:
Currently I have:

Answer 1

The col1 and col2 in your sample are Rows Groups. This name (Row Group) tell us that JasperReports engine unions all non unique values in groups in case using Crosstab component. That is why values should be always ordered for grouping data right (as shown at image below).
The data in Row Groups will be grouped by JR engine and one group is drawing as one cell.
Does this mean that the problem has no solution? - No. Let's solve it!
Looks like you want "to join" col1 and col2 columns values. This means that the value of col1 Row Group can be added to the "column" of col2 Row Group.
Example
Datasource
It is enough to test sample with simple csv datasource.
col1,col2,col3,col4,col5
abcd,1,b,1c,434
abcd,2,c,2c,333
abcd,3,c,4c,333
abcd,3,c,4c,333
abcd,5,c,4c,333
abcd,3,e,3g,909
The name of data adapter for this datasource in the example below is values.csv. The first line from the file is skipped - it is contains the column's name.
Report template
We should set the width of first column (col1 Row Group) as zero and increase the width of second column (col2 Row Group) to place additionally value of col1. In this case the JR engine draws both both values for each unique col2 value. We still need the first column because we need value of col1 (the bucket for col1 Row Group).
The design in Jaspersoft Studio (JSS) looks like:
