我正在做的项目里定义了很多样式,好像速度也不算慢,还有一些其他方面的定义,补充到下面:
//构造格式:ARIAL字体、10号、粗体、非斜体、无下划线、黑
WritableFont fmtx2TotalCaption = new WritableFont(WritableFont.ARIAL,10,WritableFont.BOLD,
false,UnderlineStyle.NO_UNDERLINE,jxl.format.Colour.BLACK);
WritableCellFormat totalx2Format = new WritableCellFormat(fmtx2TotalCaption);
//文字垂直居中对齐
totalx2Format.setVerticalAlignment(jxl.format.VerticalAlignment.CENTRE);
//文字水平居中对齐
totalx2Format.setAlignment(jxl.format.Alignment.CENTRE);
//边框深蓝
totalx2Format.setBorder(jxl.format.Border.ALL,jxl.format.BorderLineStyle.THIN,
jxl.format.Colour.DARK_BLUE);
//设置底为冰蓝
totalx2Format.setBackground(jxl.format.Colour.ICE_BLUE);
WritableFont fmtx2TotalCaption = new WritableFont(WritableFont.ARIAL,10,WritableFont.BOLD,
false,UnderlineStyle.NO_UNDERLINE,jxl.format.Colour.BLACK);
WritableCellFormat totalx2Format = new WritableCellFormat(fmtx2TotalCaption);
//文字垂直居中对齐
totalx2Format.setVerticalAlignment(jxl.format.VerticalAlignment.CENTRE);
//文字水平居中对齐
totalx2Format.setAlignment(jxl.format.Alignment.CENTRE);
//边框深蓝
totalx2Format.setBorder(jxl.format.Border.ALL,jxl.format.BorderLineStyle.THIN,
jxl.format.Colour.DARK_BLUE);
//设置底为冰蓝
totalx2Format.setBackground(jxl.format.Colour.ICE_BLUE);
Cells(0, row, 8, row); //合并单元格,row 到 row 行,0 到 8 列
sheet.setRowView(row, 600);// 第 row 行的高度
