When the crosstab columns do not fit the width, the crosstab breaks the columns and prints the ones that don't fit after printing the first set of columns for all rows. This method returns the offset to be used when continuing the printing after a column break.

public JRCrosstabCell[][] getCells()
JRCrosstab
A crosstab can have multiple data cells for row/groups totals. These cells are organized in a (rowGroupCount + 1) x (columnGroupCount + 1) matrix as following:
E.g. if the crosstab has Country and City (subgroup of Country) row groups and Year and Month column groups, the cells will be organized in the following matrix
0/Years total | 1/Months total | 2/Base | |
0/Countries total | Total for all countries and all years | Total for all countries and a year | Total for all countries and a month |
1/Cities total | Total for a country and all years | Total for a country and a year | Total for a country and a month |
2/Base | Total for a city and all years | Total for a city and a year | Total for a city and a month |
If the data cell for a total row/column is not specified, the cell will be inherited from lower levels, if possible. For example, if the "Total for all countries and a year" cell is not specified, the "Total for a country and a year" or "Total for a city and a year" cell will be used (in this order).
The data cell sizes are calculated from the base data cell sizes, i.e. the height of all data cells for a row will be the height of the base cell of that row. The base cell sizes are also inherited, e.g. if the height of a total row is not specified the height of the base row will be used.
getCells
in interface JRCrosstab
public JRCellContents getWhenNoDataCell()
JRCrosstab
If this cell is not specified for a crosstab, nothing will be rendered for an empty crosstab.
The cell sizes are the same as the crosstab element sizes.

public JRCrosstabParameter[] getParameters()
JRCrosstab
Crosstabs have separate expression evaluators and cannot access the parameters/fields/variables of the report. In order to use a value from the report inside a crosstab, it should be passed as parameter to the crosstab.
A crosstab parameters has a name and a value expression.
getParameters
in interface JRCrosstab
public JRExpression getParametersMapExpression()
JRCrosstab
The set of values for crosstab parameters can be set using a map. If a parameter has also a value expression, it will overwrite the value from the map.

null

public void setIgnoreWidth(java.lang.Boolean ignoreWidth)
JRCrosstab
This flag determines whether the crosstab will break at the width set for the crosstab element, or whether the crosstab is to expand over this width (and over the page width as well).
If this flag is set to true
, the crosstab will expand towards
the right (or towards the left if the crosstab direction is RTL) as long
as it needs to. This would result in crosstab cells being rendered over
the page boundary; such elements will be exported by certain grid-based
exporters such as the HTML or XLS ones, but will not be visible in export
formats that observe the page width, such as the PDF exporter.
The default value of this flag is given by the
JRCrosstab.PROPERTY_IGNORE_WIDTH
property and the
JRParameter.IS_IGNORE_PAGINATION
parameter.
