The idea is have a column span header, like html tables.
For example:
| State | Estimated | |
|---|---|---|
| Amount | Percentage | |
| Arizona | 600 | 30% |
| New York | 400 | 20% |
| Florida | 1000 | 50% |
In the following example, we are adding a colum span in the header of the column 2 to the column 3:
DynamicReportBuilder drb = new DynamicReportBuilder();
...
AbstractColumn columnPercentageAmount = ColumnBuilder.getNew()
.setPercentageColumn((PropertyColumn) columnAmount)
.setTitle("Amount [%]").setWidth(new Integer(90))
.setStyle(amountStyle).setHeaderStyle(headerStyle).build();
...
drb.addColumn(columnState);
drb.addColumn(columnBranch);
drb.addColumn(columnaItem);
drb.addColumn(columnaCantidad);
drb.addColumn(columnAmount);
drb.addColumn(columnPercentageAmount)
//Here set the colspan.
dbr.setColspan(2, 2, "Estimated");
...
NOTE: You may add first the cols after set the colspan.
Refer to ColumnsSpanTest for a working example.
The result is similar to:
