I want the code to export tables / reports to Excel and Word using POI. I saw the examples that came with POI but could not understand. Can anyone provide me a small/easy code to do the same.
我希望代码使用POI将表/报表导出到Excel和Word。我看到POI附带的例子但无法理解。任何人都可以为我提供一个小/简单的代码来做同样的事情。

Seeing as you wanted actual code for using POI. Here is some to do some exporting:
看到您想要使用POI的实际代码。这里有一些做一些导出:
import java.util.Date;
import java.util.List;
import java.util.ListIterator;
import java.util.StringTokenizer;
import java.io.*;
import org.apache.poi.hssf.usermodel.*;
public class XLSExporter implements Exporter {
/**
* Constructor for XLSExporter
*/
public XLSExporter(){
}
public void exportFile( File f, List o ) throws IOException{
HSSFWorkbook wb = new HSSFWorkbook();
FileOutputStream fileOut = new FileOutputStream(f);
HSSFSheet sheet = wb.createSheet();
ListIterator it = o.listIterator();
//Construct the headings
HSSFRow headingsRow = sheet.createRow((short)0);
//Heading format
HSSFFont headingFont = wb.createFont();
headingFont.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);
HSSFCellStyle headingStyle = wb.createCellStyle();
headingStyle.setAlignment(HSSFCellStyle.ALIGN_CENTER);
headingStyle.setFont(headingFont);
HSSFCell headingA = headingsRow.createCell((short)0);
headingA.setCellValue("Heading");
headingA.setCellStyle(headingStyle);
int i = 1;
// Iterate over the rows
while(it.hasNext()){
//Create the row
HSSFRow row = sheet.createRow((short)i);
//Write data
HSSFCell cellRunway = row.createCell((short)0);
cellRunway.setCellType(HSSFCell.CELL_TYPE_NUMERIC);
cellRunway.setCellValue("Whateva");
cellRunway.setCellStyle(standardStyle);
i++;
}
//Set the column widths where needed
sheet.setColumnWidth((short)1, (short)4000);
wb.write(fileOut); // Write the workbook
fileOut.close();
}
