11、借助POI實現Java生成並打印excel報表(2)

11、POI打印功能

11.1、常用模塊形式：

        HSSFPrintSetup printSetup = sheet.getPrintSetup();
        printSetup.setVResolution((short) 600);        //打印質量600點
        printSetup.setPaperSize(HSSFPrintSetup.A4_PAPERSIZE);        //A4紙張打印
        printSetup.setLandscape(true);       //橫向打印

11.2、常用參數設置方法

1、頁面設置

1.1、方向：

縱向(T)：HSSFPrintSetup#setLandscape(false); [默認狀態]

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

1.2、縮放：

縮放比例(A)：HSSFPrintSetup#setScale((short) 100); [默認狀態]

調整(F):   頁寬  HSSFPrintSetup#setFitWidth((short) 1);

頁高  HSSFPrintSetup#setFitHeight((short) 0);

1.3、紙張大小(Z)：HSSFPrintSetup#setPageSize(HSSFPrintSetup.LETTER_PAPERSIZE);

紙張大小定義說明：

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、打印質量(Q):  HSSFPrintSetup#setVResolution((short) 300);

1.5、起始頁碼(R):  HSSFPrintSetup#setPageStrart((short) 0); [默認狀態]

2、頁面距

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、頁眉(A):  HSSFPrintSetup#setHeaderMargin((double) 0.2); 

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

2.7、居中對齊方式:  水平(Z)  HSSFSheet#setHorizontallyCenter(false); 

垂直(V)  HSSFSheet#setVerticallyCenter(false); 

3、頁眉/頁腳

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

說明：首先獲得HSSFHeader對象，確定頁眉的顯示位置(如：左邊顯示頁眉HSSFHeader#setLeft(顯示內容))

可用：HSSFHeader#setLeft,setCenter,setRight

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

說明同頁眉

4、工作表

4.1、打印區域

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

參數說明： 

sheetIndex–從0開始的sheet的索引編號  
startColumn-打印區域的開始列號  
endColumn- 打印區域的結束列號  
startRow-打印區域的開始行號  
endRow- 打印區域的結束行號

4.2、打印標題

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

參數說明同上。 

使用說明：僅僅設置左端標題列：workbook.setRepeatingRowsAndColumns(0,0,1,-1,-1); 

僅僅設置頂端標題行：workbook.setRepeatingRowsAndColumns(0,-1,-1,0,4); 

同時設置左端和頂端標題：workbook.setRepeatingRowsAndColumns(0,-1,-1,-1,-1);

4.3、打印

網格線 (G)：HSSFSheet#setPrintGridlines(false); 

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

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

行號列標(L):

批注(M):

錯誤單元格打印為(E):

4.4、打印順序

HSSFPrintSetup#setLeftToRight(false)；

 11.3、程序示例:
