Usage of templates in ASPOSE Java

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
Mahesh Babu

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”);

CellsDataTableMap.java

import com.aspose.cells.*;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;

/
* DataTable class (based on ASPOSE data table object)
* 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.

public class CellsDataTableMap implements ICellsDataTable {
private List mapList = new ArrayList();
private int index;
private String[] columns = new String[]{“Name”, “Age”};
