用NPOI操作EXCEL--生成一张工资单

    这一节,我们将综合NPOI的常用功能(包括创建和填充单元格、合并单元格、设置单元格样式和利用公式),做一个工资单的实例。先看创建标题行的代码:
// 写标题文本
HSSFSheet sheet1 = hssfworkbook.CreateSheet( " Sheet1 " );
HSSFCell cellTitle
= sheet1.CreateRow( 0 ).CreateCell( 0 );
cellTitle.SetCellValue(
" XXX公司2009年10月工资单 " );

// 设置标题行样式
HSSFCellStyle style = hssfworkbook.CreateCellStyle();
style.Alignment
= HSSFCellStyle.ALIGN_CENTER;
HSSFFont font
= hssfworkbook.CreateFont();
font.FontHeight
= 20 * 20 ;
style.SetFont(font);

cellTitle.CellStyle
= style;

// 合并标题行
sheet1.AddMergedRegion( new Region( 0 , 0 , 1 , 6 ));

其中用到了我们前面讲的设置单元格样式和合并单元格等内容。接下来我们循环创建公司每个员工的工资单:

DataTable dt
= GetData();
HSSFRow row;
HSSFCell cell;
HSSFCellStyle celStyle
= getCellStyle();

HSSFPatriarch patriarch
= sheet1.CreateDrawingPatriarch();
HSSFClientAnchor anchor;
HSSFSimpleShape line;
int rowIndex;
for ( int i = 0 ; i < dt.Rows.Count; i ++ )
{
   
// 表头数据
    rowIndex = 3 * (i + 1 );
    row
= sheet1.CreateRow(rowIndex);

    cell
= row.CreateCell( 0 );
    cell.SetCellValue(
" 姓名 " );
    cell.CellStyle
= celStyle;

    cell
= row.CreateCell( 1 );
    cell.SetCellValue(
" 基本工资 " );
    cell.CellStyle
= celStyle;

    cell
= row.CreateCell( 2 );
    cell.SetCellValue(
" 住房公积金 " );
    cell.CellStyle
= celStyle;

    cell
= row.CreateCell( 3 );
    cell.SetCellValue(
" 绩效奖金 " );
    cell.CellStyle
= celStyle;

    cell
= row.CreateCell( 4 );
    cell.SetCellValue(
" 社保扣款 " );
    cell.CellStyle
= celStyle;

    cell
= row.CreateCell( 5 );
    cell.SetCellValue(
" 代扣个税 " );
    cell.CellStyle
= celStyle;

    cell
= row.CreateCell( 6 );
    cell.SetCellValue(
" 实发工资 " );
    cell.CellStyle
= celStyle;


    DataRow dr
= dt.Rows[i];
   
// 设置值和计算公式
    row = sheet1.CreateRow(rowIndex + 1 );
    cell
= row.CreateCell( 0 );
    cell.SetCellValue(dr[
" FName " ].ToString());
    cell.CellStyle
= celStyle;

    cell
= row.CreateCell( 1 );
    cell.SetCellValue((
double )dr[ " FBasicSalary " ]);
    cell.CellStyle
= celStyle;

    cell
= row.CreateCell( 2 );
    cell.SetCellValue((
double )dr[ " FAccumulationFund " ]);
    cell.CellStyle
= celStyle;

    cell
= row.CreateCell( 3 );
    cell.SetCellValue((
double )dr[ " FBonus " ]);
    cell.CellStyle
= celStyle;

    cell
= row.CreateCell( 4 );
    cell.SetCellFormula(String.Format(
" $B{0}*0.08 " ,rowIndex + 2 ));
    cell.CellStyle
= celStyle;

    cell
= row.CreateCell( 5 );
    cell.SetCellFormula(String.Format(
" SUM($B{0}:$D{0})*0.1 " ,rowIndex + 2 ));
    cell.CellStyle
= celStyle;

    cell
= row.CreateCell( 6 );
    cell.SetCellFormula(String.Format(
" SUM($B{0}:$D{0})-SUM($E{0}:$F{0}) " ,rowIndex + 2 ));
    cell.CellStyle
= celStyle;


   
// 绘制分隔线
    sheet1.AddMergedRegion( new Region(rowIndex + 2 , 0 , rowIndex + 2 , 6 ));
    anchor
= new HSSFClientAnchor( 0 , 125 , 1023 , 125 , 0 , rowIndex + 2 , 6 , rowIndex + 2 );
    line
= patriarch.CreateSimpleShape(anchor);
    line.ShapeType
= HSSFSimpleShape.OBJECT_TYPE_LINE;
    line.LineStyle
= HSSFShape.LINESTYLE_DASHGEL;

}
其中为了文件打印为单元格增加了黑色边框的样式(如果不设置边框样式,打印出来后是没有边框的)。另外,注意循环过程中excel中的行号随数据源中的行号变化处理。完整代码如下:
