通过POI来进行单元格格式的设定

设定格式使用「HSSFCellStyle」类。它有一个构造方法：

protected HSSFCellStyle(short index, ExtendedFormatRecord rec)
虽然有构造方法，但却是protected的，所以不能直接使用，要通过一个工作簿workbook来生成格式对象。

在POI里，格式好像是以workbook为单位来管理的，所以要先作成一个格式对象，保存在workbook里，然后再对已生成好的单元格进行设定。

在单元格里指定格式

1，要作成一个格式对象，可以使用「HSSFWorkbook」类的「createCellStyle」方法。
public HSSFCellStyle createCellStyle()
2，要取出现有的格式对象的话，使用「HSSFWorkbook」类的「getCellStyleAt」方法，这个方法有参数，是被保存格式的INDEX号。
public HSSFCellStyle getCellStyleAt(short idx)
3，对于某一个单元格，也可以取出它的格式对象。这时要使用「HSSFCell」类的「getCellStyle」方法。
public HSSFCellStyle getCellStyle()
4，这样的话，不管是新创建的或者是从现有的单元格里取出来的格式对象，都可以用来对某一个单元格进行格式的设定。设定方法使用「HSSFCell」类的「setCellStyle」方法。
public void setCellStyle(HSSFCellStyle style)

package linkin;

import java.io.FileOutputStream;
import java.io.IOException;

import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFCellStyle;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.hssf.util.HSSFColor;

public class Linkin
{
	public static void main(String[] args)
	{
		HSSFWorkbook workbook = new HSSFWorkbook();

		HSSFSheet sheet = workbook.createSheet();
		HSSFRow row = sheet.createRow(1);//第二行

		HSSFCell cell = row.createCell(0);//2,1格
		cell.setCellValue("sample");//写入sample

		HSSFCellStyle style = workbook.createCellStyle();//创建个workbook的HSSFCellStyle格式对象style

		//设定格式
		style.setFillBackgroundColor(HSSFColor.WHITE.index);
		style.setFillForegroundColor(HSSFColor.LIGHT_ORANGE.index);
		style.setFillPattern(HSSFCellStyle.THICK_HORZ_BANDS);

		cell.setCellStyle(style);//对2,1格写入上面的格式

		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());
			}
		}
	}
}

POI单元格颜色设定

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。
1，前景色的设定使用「HSSFCellStyle」类的「setFillForegroundColor」方法。
public void setFillForegroundColor(short bg)

2，背景色的设定则使用「HSSFCellStyle」类的「setFillBackgroundColor」方法。
public void setFillBackgroundColor(short bg)
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：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，那么下面介绍怎么设定自己想要的顔色。

填充模式

1，指定填充模式的话，使用「HSSFCellStyle」类的「setFillPattern」方法。
public void setFillPattern(short fp)

2，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);

package linkin;

import java.io.FileOutputStream;
import java.io.IOException;

import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.hssf.util.HSSFColor;

public class Linkin
{
	static HSSFWorkbook workbook;

	public static void main(String[] args)
	{

		setStyle(cell[11][1], "WHITE", HSSFColor.WHITE.index);
		setStyle(cell[11][2], "YELLOW", HSSFColor.YELLOW.index);

		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

上面固定了「ForegroundColor」和「BackgroundColor」，而填充模式则做了各种尝试

POI设置边框

在做一个电子表格时，边框的设置有时是必不可少的。这一节就来介绍边框，设置时，可以指定边框的位置，边框的种类，边框的顔色。首先是边框的位置和种类。对单元格设置边框时，有上下左右位置之分，所以POI也准备了四个不同的方法。
上部的边框： public void setBorderTop(short border)
下部的边框： public void setBorderBottom(short border)
左侧的边框： public void setBorderLeft(short border)
右侧的边框： public void setBorderRight(short border)

参数通过表示边框种类的short型值来指定。下面是定义在「HSSFCellStyle」类里可以被指定值的一览表。
值说明
BORDER_DASH_DOT dash-dot border
BORDER_DASH_DOT_DOT dash-dot-dot border
BORDER_DASHED dash border
BORDER_DOTTED dot borderhair-line border
BORDER_DOUBLE double-line border
BORDER_HAIR hair-line border
BORDER_MEDIUM Medium border
BORDER_MEDIUM_DASH_DOT medium dash-dot border
BORDER_MEDIUM_DASH_DOT_DOT medium dash-dot-dot border
BORDER_MEDIUM_DASHED Medium dashed border
BORDER_NONE No border
BORDER_SLANTED_DASH_DOT slanted dash-dot border
BORDER_THICK Thick border
BORDER_THIN Thin border

比如要在单元格下边框设置两重线的边框时，按如下方法：

HSSFWorkbook workbook = new HSSFWorkbook();
HSSFCellStyle style = workbook.createCellStyle();
style.setBorderRight(HSSFCellStyle.BORDER_THIN);

下面再看看指定边框顔色。同样也分为上下左右边框来操作。
上部的边框： public void setTopBorderColor(short color)
下部的边框： public void setBottomBorderColor(short color)
左侧的边框： public void setLeftBorderColor(short color)
右侧的边框： public void setRightBorderColor(short color)

仍然是通过参数来指定顔色，而且使用方法和前面一节也是一样。具体如下：

HSSFWorkbook workbook = new HSSFWorkbook();
HSSFCellStyle style = workbook.createCellStyle();
style.setRightBorderColor(HSSFColor.RED.index);
style.setBorderRight(HSSFCellStyle.BORDER_THIN);

package linkin;

import java.io.FileOutputStream;
import java.io.IOException;

import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFCellStyle;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.hssf.util.HSSFColor;

public class Linkin
{
	public static void main(String[] args)
	{
		HSSFWorkbook workbook = new HSSFWorkbook();
		HSSFSheet sheet = workbook.createSheet();

		HSSFRow row = sheet.createRow(1);
		HSSFCell cell1 = row.createCell((short) 1);
		HSSFCell cell2 = row.createCell((short) 2);

		HSSFCellStyle style1 = workbook.createCellStyle();
		style1.setBorderTop(HSSFCellStyle.BORDER_DOUBLE);
		style1.setBorderLeft(HSSFCellStyle.BORDER_DOUBLE);
		style1.setTopBorderColor(HSSFColor.GOLD.index);
		style1.setLeftBorderColor(HSSFColor.PLUM.index);
		cell1.setCellStyle(style1);

		HSSFCellStyle style2 = workbook.createCellStyle();
		style2.setBorderBottom(HSSFCellStyle.BORDER_DOUBLE);
		style2.setBorderRight(HSSFCellStyle.BORDER_DOUBLE);
		style2.setBottomBorderColor(HSSFColor.ORANGE.index);
		style2.setRightBorderColor(HSSFColor.SKY_BLUE.index);
		cell2.setCellStyle(style2);

		cell1.setCellValue("U & L");
		cell2.setCellValue("B & R");

		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());
			}
		}
	}
}

上面程序既改了顔色，也设置了上和左的边框各一个，右和下的边框各一个。
