設定格式使用「HSSFCellStyle」類。它有一個構造方法:java
protected HSSFCellStyle(short index, ExtendedFormatRecord rec)在POI裏,格式好像是以workbook爲單位來管理的,因此要先做成一個格式對象,保存在workbook裏,而後再對已生成好的單元格進行設定。 apache
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");//寫入sample HSSFCellStyle style = workbook.createCellStyle();//建立個workbook的HSSFCellStyle格式對象style //設定格式 style.setFillBackgroundColor(HSSFColor.WHITE.index); style.setFillForegroundColor(HSSFColor.LIGHT_ORANGE.index); style.setFillPattern(HSSFCellStyle.THICK_HORZ_BANDS); cell.setCellStyle(style);//對2,1格寫入上面的格式 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()); } } } }
2,背景色的設定則使用「HSSFCellStyle」類的「setFillBackgroundColor」方法。
public void setFillBackgroundColor(short bg)
兩個方法都是經過參數來設定具體什麼顔色。該參數類型爲short型,在「HSSFColor」類裏,準備了各類各樣顔色的定義值。 ide
HSSFWorkbook workbook = new HSSFWorkbook(); HSSFCellStyle style = workbook.createCellStyle(); style.setFillForegroundColor(HSSFColor.LIME.index); style.setFillBackgroundColor(HSSFColor.GREEN.index);
HSSFWorkbook workbook = new HSSFWorkbook(); HSSFCellStyle style = workbook.createCellStyle(); style.setFillForegroundColor(HSSFColor.LIME.index); style.setFillBackgroundColor(HSSFColor.GREEN.index); style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);

上面程序只指定了「ForegroundColor」,填充模式是「SOLID_FOREGROUND」,所以顔色應該是所有充滿整個單元格的spa

上面固定了「ForegroundColor」和「BackgroundColor」,而填充模式則作了各類嘗試code
好比要在單元格下邊框設置兩重線的邊框時,按以下方法:
orm
HSSFWorkbook workbook = new HSSFWorkbook(); HSSFCellStyle style = workbook.createCellStyle(); style.setBorderRight(HSSFCellStyle.BORDER_THIN);
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,也設置了上和左的邊框各一個,右和下的邊框各一個。 對象
