jxl加邊框

WritableWorkbook wwb = Workbook.createWorkbook(os);

WritableSheet ws = wwb.createSheet( "TestSheet1 ", 0);

WritableFont wf = newWritableFont(WritableFont.TIMES, 18, WritableFont.BOLD, true);

WritableCellFormat wcf = new WritableCellFormat(wf);

wcf.setBorder(jxl.format.Border.ALL, jxl.format.BorderLineStyle.THIN);

Label labelcf = new Label(1, 0, "this is a label with border test ", wcf);

ws.addCell(labelcf);

wwb.write();

wwb.close();

jxl合并單元格

public static void writeExcel(OutputStream os )throws Exception

{

try

{

jxl.write.WritableWorkbook wwb = Workbook.createWorkbook(os);

// jxl.write.WritableSheet ws = wwb.createSheet("TestSheet1", 0);

jxl.write.WritableSheet ws = wwb.createSheet("testsheet1", 0);

jxl.write.Label labelC = new jxl.write.Label(0, 0, "我愛中國");

ws.addCell(labelC);

labelC = new jxl.write.Label(1, 2, "我愛中國1,2");

ws.addCell(labelC);

jxl.write.WritableFont wfc = new jxl.write.WritableFont(WritableFont.ARIAL, 20,

WritableFont.BOLD, false,

UnderlineStyle.NO_UNDERLINE, jxl.format.Colour.GREEN);

jxl.write.WritableCellFormat wcfFc = new jxl.write.WritableCellFormat(wfc);

labelC = new jxl.write.Label(6, 0, "中國我愛", wcfFc);

ws.addCell(labelC);

WritableFont wf_merge = new WritableFont(WritableFont.ARIAL, 10, WritableFont.NO_BOLD,

false, UnderlineStyle.DOUBLE_ACCOUNTING, jxl.format.Colour.GREEN);

WritableCellFormat wff_merge = new WritableCellFormat(wf_merge);

// wff_merge.setBackground(jxl.format.Colour.BLACK);

jxl.write.Label label30 = new Label(3, 0, "Label30", wff_merge);

ws.addCell(label30);

//合并單元格

ws.mergeCells(3, 0, 4, 0);

wwb.write();

wwb.close();

}

catch (Exception e )

{

throw e;

}

}

使用WritableCellFormat 的setWrap(true)可以設成自動換行，然后再用WritableSheet的setRowView設置行的高度，setColumnView設置列的寬度

行高和列寬

WritableSheet.setRowView(int i, int height);

作用是指定第i + 1行的高度，比如：

//將第一行的高度設為200

sheet.setRowView(0, 200);

WritableSheet.setColumnView(int i, int width);

作用是指定第i + 1列的寬度，比如：

//將第一列的寬度設為30

sheet.setColumnView(0, 30);

單元格居中

Label label = new Label(column, row, labelValue);

WritableCellFormat cellFormat = new WritableCellFormat();

cellFormat.setAlignment(jxl.format.Alignment.CENTER);

label.setCellFormat(cellFormat);

sheetWrite.addCell(label);
