Usage of templates in ASPOSE Java

Aspose.Cells Product Family
1

Hi,

We are using the template for report generation using ASPOSE .NET cells. Now, we are planning to migrate from code from .NET to Java. I would like to is there any equivalent of usage of markers in Java such as:
&=dvCAdequacyHeaderAccts.VALUE_AMT1

where
dvCAdequacyHeaderAccts is datatable name.
VALUE_AMT1 is column name.

I would like to if there is equivalent to datatable can be passed
param.MarkerProcessor.SetDataSource(DataTable);

Thanks

Hi Mahesh,

Thanks for your posting and using Aspose.Cells for Java.

You can implement ICellsDataTable interface as shown below and then set your data source.

I have attached the sample xlsx file used in this code and output xlsx file generated by it for your reference.

Java
String filePath = “F:\Shak-Data-RW\Downloads\sample.xlsx”;

Workbook workbook = new Workbook(filePath);
WorkbookDesigner designer = new WorkbookDesigner(workbook);

CellsDataTableMap dataTable = new CellsDataTableMap();

designer.setDataSource(“dvCAdequacyHeaderAccts”, dataTable);

designer.process();

workbook.save(filePath + “.out.xlsx”);

* Has the member “mapList”. This will contain a list of elements parsed from the source XML file.
* The methods are called by the ASPOSE API when “designerobject.process” is executed.
