POI单元格顔色设定

十一月 30th, 2009 |

Author: braveheart_txl

先从单元格顔色设定开始介绍。单元格的顔色有前景色和背景色。

前景色的设定使用「HSSFCellStyle」类的「setFillForegroundColor」方法。

setFillForegroundColor
public void setFillForegroundColor(short bg)

set the foreground fill color
Parameters:
bg - color

背景色的设定则使用「HSSFCellStyle」类的「setFillBackgroundColor」方法。

setFillBackgroundColor
public void setFillBackgroundColor(short bg)

set the background fill color.
Parameters:
bg - color

两个方法都是通过参数来设定具体什么顔色。该参数类型为short型，在「HSSFColor」类里，准备了各种各样顔色的定义值。

HSSFColor类

HSSFColor类定义如下：

java.lang.Object
org.apache.poi.hssf.util.HSSFColor
public class HSSFColor extends java.lang.Object

而各种顔色又是作为HSSFColor类的子类，定义一览表如下：

HSSFColor.AQUA	HSSFColor.BLACK
HSSFColor.BLUE	HSSFColor.BLUE_GREY
HSSFColor.BRIGHT_GREEN	HSSFColor.BROWN
HSSFColor.CORAL	HSSFColor.CORNFLOWER_BLUE
HSSFColor.DARK_BLUE	HSSFColor.DARK_GREEN
HSSFColor.DARK_RED	HSSFColor.DARK_TEAL
HSSFColor.DARK_YELLOW	HSSFColor.GOLD
HSSFColor.GREEN	HSSFColor.GREY_25_PERCENT
HSSFColor.GREY_40_PERCENT	HSSFColor.GREY_50_PERCENT
HSSFColor.GREY_80_PERCENT	HSSFColor.INDIGO
HSSFColor.LAVENDER	HSSFColor.LEMON_CHIFFON
HSSFColor.LIGHT_BLUE	HSSFColor.LIGHT_CORNFLOWER_BLUE
HSSFColor.LIGHT_GREEN	HSSFColor.LIGHT_ORANGE
HSSFColor.LIGHT_TURQUOISE	HSSFColor.LIGHT_YELLOW
HSSFColor.LIME	HSSFColor.MAROON
HSSFColor.OLIVE_GREEN	HSSFColor.ORANGE
HSSFColor.ORCHID	HSSFColor.PALE_BLUE
HSSFColor.PINK	HSSFColor.PLUM
HSSFColor.RED	HSSFColor.ROSE
HSSFColor.ROYAL_BLUE	HSSFColor.SEA_GREEN
HSSFColor.SKY_BLUE	HSSFColor.TAN
HSSFColor.TEAL	HSSFColor.TURQUOISE
HSSFColor.VIOLET	HSSFColor.WHITE
HSSFColor.YELLOW

设定顔色时，用这些子类的静态常量「index」作为参数，使用方法如下：

HSSFWorkbook workbook = new HSSFWorkbook();
HSSFCellStyle style = workbook.createCellStyle();
style.setFillForegroundColor(HSSFColor.LIME.index);
style.setFillBackgroundColor(HSSFColor.GREEN.index);

如果这些顔色还不够你用的话，那么下一节再介绍怎么设定自己想要的顔色。

填充模式

指定填充模式的话，使用「HSSFCellStyle」类的「setFillPattern」方法。

setFillPattern
public void setFillPattern(short fp)

setting to one fills the cell with the foreground color
... No idea about other values
Parameters:
fp - fill pattern (set to 1 to fill w/foreground color)

指定的填充模式，在「HSSFCellStyle」类里也有定义，类型为static short型，如下所示：

值	说明
NO_FILL	No background
SOLID_FOREGROUND	Solidly filled
FINE_DOTS	Small fine dots
ALT_BARS	Wide dots
SPARSE_DOTS	Sparse dots
THICK_HORZ_BANDS	Thick horizontal bands
THICK_VERT_BANDS	Thick vertical bands
THICK_BACKWARD_DIAG	Thick backward facing diagonals
THICK_FORWARD_DIAG	Thick forward facing diagonals
BIG_SPOTS	Large spots
BRICKS	Brick-like layout
THIN_HORZ_BANDS	Thin horizontal bands
THIN_VERT_BANDS	Thin vertical bands
THIN_BACKWARD_DIAG	Thin backward diagonal
THIN_FORWARD_DIAG	Thin forward diagonal
SQUARES	Squares
DIAMONDS	Diamonds

实际的使用方法如下：

HSSFWorkbook workbook = new HSSFWorkbook();
HSSFCellStyle style = workbook.createCellStyle();
style.setFillForegroundColor(HSSFColor.LIME.index);
style.setFillBackgroundColor(HSSFColor.GREEN.index);
style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);

示例程序

这就实际动手做做看吧，首先看一下定义的顔色到底是什么顔色，全部拉上来看看。

import java.io.*;

FileOutputStream out = null;
try{
out = new FileOutputStream("sample.xls");
workbook.write(out);
}catch(IOException e){
System.out.println(e.toString());
}finally{
try {
out.close();
}catch(IOException e){
System.out.println(e.toString());
}
}
}
public static void setStyle(HSSFCell cell, String col, short fg){
HSSFCellStyle style = workbook.createCellStyle();
style.setFillForegroundColor(fg);
style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);
cell.setCellStyle(style);
cell.setCellValue(col);
}
}

上面程序只指定了「ForegroundColor」，填充模式是「SOLID_FOREGROUND」，因此顔色应该是全部充满整个单元格的。运行结果如下：

顔色指定

下面再对填充模式进行各种修改来看看。

for (int i = 0; i < 5 ; i++){
row[i] = sheet.createRow(i);
}

for (int i = 0; i < 5; i++){
for (int j = 0; j < 4 ; j++){
cell[i][j] = row[i].createCell((short)j);
}
}
setStyle(cell[0][0], "NO_FILL", HSSFCellStyle.NO_FILL);
setStyle(cell[0][1], "SOLID_FOREGROUND",
HSSFCellStyle.SOLID_FOREGROUND);
setStyle(cell[0][2], "FINE_DOTS", HSSFCellStyle.FINE_DOTS);

setStyle(cell[2][1], "BIG_SPOTS", HSSFCellStyle.BIG_SPOTS);
setStyle(cell[2][2], "BRICKS", HSSFCellStyle.BRICKS);
setStyle(cell[2][3], "THIN_HORZ_BANDS",

setStyle(cell[3][0], "THIN_VERT_BANDS",

setStyle(cell[3][1], "THIN_BACKWARD_DIAG",
HSSFCellStyle.THIN_BACKWARD_DIAG);
setStyle(cell[3][2], "THIN_FORWARD_DIAG",
HSSFCellStyle.THIN_FORWARD_DIAG);
setStyle(cell[3][3], "SQUARES", HSSFCellStyle.SQUARES);
setStyle(cell[4][0], "DIAMONDS", HSSFCellStyle.DIAMONDS);
FileOutputStream out = null;
try{
out = new FileOutputStream("sample.xls");
workbook.write(out);
}catch(IOException e){
System.out.println(e.toString());
}finally{
try {
out.close();
}catch(IOException e){
System.out.println(e.toString());
}
}
}
public static void setStyle(HSSFCell cell, String fps,
short fp){
HSSFCellStyle style = workbook.createCellStyle();
style.setFillForegroundColor(HSSFColor.WHITE.index);
style.setFillForegroundColor(HSSFColor.LIGHT_ORANGE.index);
style.setFillPattern(fp);
cell.setCellStyle(style);
cell.setCellValue(fps);
}
}

上面固定了「ForegroundColor」和「BackgroundColor」，而填充模式则做了各种尝试。运行结果如下：
