11、借助POI实现Java生成并打印excel报表(2)

11、POI打印功能

11.1、常用模块形式：

         HSSFPrintSetup printSetup = sheet.getPrintSetup();
         printSetup.setVResolution((short) 600);        //打印质量600点
         printSetup.setPaperSize(HSSFPrintSetup.A4_PAPERSIZE);        //A4纸张打印
         printSetup.setLandscape(true);       //横向打印

11.2、常用参数设置方法

1、页面设置

1.1、方向：

纵向(T)：HSSFPrintSetup#setLandscape(false); [默认状态]

横向(L)：HSSFPrintSetup#setLandscape(true);

1.2、缩放：

缩放比例(A)：HSSFPrintSetup#setScale((short) 100); [默认状态]

调整(F):   页宽  HSSFPrintSetup#setFitWidth((short) 1);

页高  HSSFPrintSetup#setFitHeight((short) 0);

1.3、纸张大小(Z)：HSSFPrintSetup#setPageSize(HSSFPrintSetup.LETTER_PAPERSIZE);

纸张大小定义说明：

public static final short LETTER_PAPERSIZE = 1;

public static final short LEGAL_PAPERSIZE = 5;

public static final short EXECUTIVE_PAPERSIZE = 7;

public static final short A4_PAPERSIZE = 9;

public static final short A5_PAPERSIZE = 11;

public static final short ENVELOPE_10_PAPERSIZE = 20;

public static final short ENVELOPE_DL_PAPERSIZE = 27;

public static final short ENVELOPE_CS_PAPERSIZE = 28;

public static final short ENVELOPE_MONARCH_PAPERSIZE = 37;

1.4、打印质量(Q):  HSSFPrintSetup#setVResolution((short) 300);

1.5、起始页码(R):  HSSFPrintSetup#setPageStrart((short) 0); [默认状态]

2、页面距

2.1、上(T):  HSSFSheet#setMargin(HSSFSheet.TopMargin,(short) 0.6);

2.2、下(B):  HSSFSheet#setMargin(HSSFSheet.BottomMargin,(short) 0.6);

2.3、左(L):  HSSFSheet#setMargin(HSSFSheet.LeftMargin,(short) 0.6);

2.4、右(R):  HSSFSheet#setMargin(HSSFSheet.RightMargin,(short) 0.2);

2.5、页眉(A):  HSSFPrintSetup#setHeaderMargin((double) 0.2);

2.6、页脚(F):  HSSFPrintSetup#setFooterMargin((double) 0.6);

2.7、居中对齐方式:  水平(Z)  HSSFSheet#setHorizontallyCenter(false);

垂直(V)  HSSFSheet#setVerticallyCenter(false);

3、页眉/页脚

3.1、页眉：HSSFHeader#setLeft（HSSFHeader.date();

说明：首先获得HSSFHeader对象，确定页眉的显示位置(如：左边显示页眉HSSFHeader#setLeft(显示内容))

可用：HSSFHeader#setLeft,setCenter,setRight

3.2、页脚:  HSSFFotter#setLeft（HSSFFotter.page()+”/”+HSSFFotter.numPages()）

说明同页眉

4、工作表

4.1、打印区域

HSSFWorkbook#setPrintArea((int) sheetIndex,  (int) startColumn,  (int) endColumn,  (int) startRow,  (int) endRow);

参数说明：

sheetIndex–从0开始的sheet的索引编号  
startColumn-打印区域的开始列号  
endColumn- 打印区域的结束列号  
startRow-打印区域的开始行号  
endRow- 打印区域的结束行号

4.2、打印标题

HSSFWorkbook#setRepeatingRowsAndColumns((int) sheetIndex,  (int) startColumn,  (int) endColumn,  (int) startRow,  (int) endRow);

参数说明同上。

使用说明：仅仅设置左端标题列：workbook.setRepeatingRowsAndColumns(0,0,1,-1,-1);

仅仅设置顶端标题行：workbook.setRepeatingRowsAndColumns(0,-1,-1,0,4);

同时设置左端和顶端标题：workbook.setRepeatingRowsAndColumns(0,-1,-1,-1,-1);

4.3、打印

网格线 (G)：HSSFSheet#setPrintGridlines(false);

单色打印(B)HSSFPrintSetup#setNoColor(false);

按草稿方式（Q）：HSSFPrintSetup#setDraft(false)；

行号列标(L):

批注(M):

错误单元格打印为(E):

4.4、打印顺序

HSSFPrintSetup#setLeftToRight(false)；

11.3、程序示例:
