NPOI版本:2.1.3.1 我有这个代码,它正在改变孔板的颜色而不仅仅是单元格...更改单元格填充颜色的正确方法是什么?
以下是工作代码,基于下面标记为正确的答案:
XSSFWorkbook hssfwb;
using (FileStream file = new FileStream(@"D:\Copy D\Tech\VB\XLSX teste com NPOI\XLSX 1\Book1.xlsx", FileMode.Open, FileAccess.Read))
{
hssfwb = new XSSFWorkbook(file);
file.Close();
}
ISheet sheet = hssfwb.GetSheetAt(0);
IRow row = sheet.GetRow(0);
ICellStyle testeStyle = hssfwb.CreateCellStyle();
testeStyle.BorderBottom = NPOI.SS.UserModel.BorderStyle.Medium;
testeStyle.FillForegroundColor = IndexedColors.BrightGreen.Index;
testeStyle.FillPattern = FillPattern.SolidForeground;
ICell cell = row.CreateCell(5);
cell.SetCellValue("testeeerere");
cell.CellStyle = testeStyle;
using (FileStream file = new FileStream(@"D:\Copy D\Tech\VB\XLSX teste com NPOI\XLSX 1\Book1ee22.xlsx", FileMode.Create, FileAccess.Write))
{
hssfwb.Write(file);
file.Close();
}
答案 0 :(得分:21)
看一下这个例子:
using NPOI.HSSF.UserModel;
using NPOI.SS.UserModel;
using NPOI.SS.Util;
(...)
Row row = sheet.CreateRow(0);
//styling
Font boldFont = workbook.CreateFont();
boldFont.Boldweight = (short)FontBoldWeight.BOLD;
ICellStyle boldStyle = workbook.CreateCellStyle();
boldStyle.SetFont(boldFont);
boldStyle.BorderBottom = CellBorderType.MEDIUM;
boldStyle.FillForegroundColor = NPOI.HSSF.Util.HSSFColor.GREY_25_PERCENT.index;
boldStyle.FillPattern = FillPatternType.SOLID_FOREGROUND;
for (int i = 0; i < columns.Length; i++)
{
Cell cell = row.CreateCell(i);
cell.SetCellValue(columns[i]);
cell.CellStyle = boldStyle;
}
在这里,您可以看到如何为一行中的每个单元格应用粗体,背景颜色和边框。在此示例中,columns
是表示列数据的字符串数组;请改用你的价值观。
