POI中关于背景色的使用

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

The generated excel files looks like below images.
