POI导出Excel设置单元格背景色

POI导出Excel设置单元格背景色

导出Excel的时候，没有设置背景色，用2003版本的Excel工具打开会出现文档单元格背景自动填充黑色的情况，没有找到好的解决方法，就主动给他填充一种颜色，问题就算解决了。在WPS中似乎会自动将黑色改为白色，所以我用WPS看不到填充黑色的情况。

This example shows you Excel cell fills and colors using Apache POI.

In our example i have used all the possible colors and set it as Fills background colors of cells.

Below is the example code.

package com.java.connect.poi;
 
import java.io.FileOutputStream;
import java.io.IOException;
 
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;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

注意：

（1）必须调用设置前景色的方法来设置背景色；

（2）必须调用setFillPattern()方法设置全填充。
