java使用jxl创建excel表格由于行列有限制，推荐使用poi

简单记录下 使用jxl创建excel遇到的坑

1、异常错误

2、异常分析 

出现了警告 Could not add cell at A257 because it exceeds the maximum column limit，原因在于jxl 使用的是excel 2003，excel 2003列限制和行限制分别是256和65536。当写257行时就提示了改异常。

3、解决 

使用excel 2007代替excel 2003,excel 2007限制行数和列数为1048576和16384。

由于jxl这个包创建的excel 是2003版的，因此引入了poi包来替换jxl。

4、jxl 和 poi创建excel的代码实现

以下分别介绍jxl 和 poi创建excel的方法：

jxl创建excel的代码：

package com.best.oasis.ltlv5.report;

import jxl.Workbook;
import jxl.format.Colour;
import jxl.write.*;

import java.io.FileOutputStream;
import java.io.OutputStream;

public class JxlExcelTest {
public static void main(String[] args) {
WritableWorkbook workbook;
String excelPath = "d:\\temp\\bb" + "测试" + System.currentTimeMillis() + ".xls";
try {
OutputStream os = new FileOutputStream(excelPath);
workbook = Workbook.createWorkbook(os);

WritableSheet ws = workbook.createSheet("test", workbook.getSheetNames().length);
ws.getSettings().setDefaultColumnWidth(10);
ws.getSettings().setHorizontalFreeze(2);
ws.getSettings().setVerticalFreeze(2);

//样式
WritableCellFormat titleWritableCellFormat = createTileWritableCellFormat();
WritableCellFormat textWritableCellFormat = createTextWritableCellFormat();

int row = 0;
for (int i = 0; i <= 100; i++) {
//创建合并的单元格
Label lbTitle = new Label(2 * i, row, "标题" + 2 * i, titleWritableCellFormat);
ws.addCell(lbTitle);
ws.mergeCells(2 * i, row, 2 * i + 1, row + 1); //startCol startRow endCol endRow
}

//添加普通单元格
for (int j = 2; j < 100; j++) {
for (int i = 0; i <= 100; i++) {
ws.addCell(new Label(2 * i, j, "内容" + j + "行" + (2 * i) + "列", textWritableCellFormat));
ws.addCell(new Label(2 * i + 1, j, "内容" + j + "行" + (2 * i + 1) + "列", textWritableCellFormat));
}
}

workbook.write();
workbook.close();
//workbook.write(outputStream);
//outputStream.close();
} catch (Exception e) {
System.out.println("It cause Error on WRITTING excel workbook: ");
e.printStackTrace();
}

}

private static WritableCellFormat createTileWritableCellFormat() throws WriteException {
WritableFont font = new WritableFont(WritableFont.TIMES, 14, WritableFont.BOLD, false);
font.setColour(Colour.RED);
WritableCellFormat cellFormat = new WritableCellFormat(font);
cellFormat.setBackground(jxl.format.Colour.LIGHT_TURQUOISE);

setCommonWritableCellFormat(cellFormat);

return cellFormat;
}

private static WritableCellFormat createTextWritableCellFormat() throws WriteException {
WritableFont font = new WritableFont(WritableFont.TIMES, 10, WritableFont.NO_BOLD, false);
WritableCellFormat cellFormat = new WritableCellFormat(font);
setCommonWritableCellFormat(cellFormat);
return cellFormat;
}

private static void setCommonWritableCellFormat(WritableCellFormat cellFormat) throws WriteException {
// 对齐方式
cellFormat.setAlignment(jxl.format.Alignment.CENTRE);
cellFormat.setVerticalAlignment(jxl.format.VerticalAlignment.CENTRE);
// 边框
cellFormat.setBorder(jxl.format.Border.ALL, jxl.format.BorderLineStyle.THIN);
// 自动换行
cellFormat.setWrap(true);
}

}


poi创建excel的代码：

Row row0 = sheet.createRow(0);
