Question

我正在使用Apache POI生成一些报告，而我在设计Rows时遇到了问题。当我打开生成的excel文件时，行的样式在第25列之后开始，我已经尝试了所有内容并且无法找出原因..

以下是代码：

import java.io.FileOutputStream;
import java.io.IOException;
import java.util.LinkedHashMap;

import org.apache.poi.EncryptedDocumentException;
import org.apache.poi.hssf.usermodel.HSSFCellStyle;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.hssf.util.HSSFColor;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.CellStyle;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;


public class PrintExcel {

static void print(LinkedHashMap<RowReport,RowReport> map, String fileName) {

    try {               

        Workbook wb = new HSSFWorkbook();   
        Sheet sheet = wb.createSheet("DiffReport");

        int iterator_row = 0,iterator_cell = 0;

        CellStyle style = wb.createCellStyle();
        style.setFillForegroundColor(HSSFColor.RED.index);
        style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);

        //Iterate through rows

        for(RowReport row : map.keySet()) {

            Row rowDestination = sheet.createRow((short)iterator_row);  

            //cellDestination.setCellStyle(style);

            for(iterator_cell = 0; iterator_cell <= 25; iterator_cell++) {

                Cell cellDestination = rowDestination.createCell(iterator_cell);

                switch (iterator_cell) {

                    case 0:

您需要致电

[]

在你的for循环中

终止于索引＆lt; = 25。

您只能在此循环结束后调用

Apache POI没有样式整行
