private void buildSheet(HSSFWorkbook wb, DataTable data, string sheetName)
{
var cHelp = wb.GetCreationHelper();
var sheet = wb.CreateSheet(sheetName);
HSSFFont hFont = (HSSFFont)wb.CreateFont();
hFont.Boldweight = (short)FontBoldWeight.Bold;
hFont.Color = HSSFColor.White.Index;
hFont.FontHeightInPoints = 18;

hStyle.SetFont(hFont);
hStyle.BorderBottom = BorderStyle.Medium;
hStyle.FillBackgroundColor = HSSFColor.Black.Index;
IRow headerRow = sheet.CreateRow(1);
int cellCount = 1;
foreach (string str in colHeaders)
{
HSSFCell cell = (HSSFCell)headerRow.CreateCell(cellCount);
cell.SetCellValue(cHelp.CreateRichTextString((str)));
cell.CellStyle = hStyle;
cellCount += 1;
}
int rowCount = 2;
foreach (DataRow dr in data.Rows)
{
var row = sheet.CreateRow(rowCount);
for (int i = 1; i < data.Columns.Count + 1; i++)
{
row.CreateCell(i).SetCellValue(cHelp.CreateRichTextString((dr[i - 1]).ToString()));
}
rowCount += 1;
}
}
private void buildSheet(HSSF工作簿wb、数据表数据、字符串sheetName)
{
var cHelp=wb.GetCreationHelper();
var sheet=wb.CreateSheet(sheetName);
hssfont hFont=(hssfont)wb.CreateFont();
hFont.Boldweight=(短)fontboldwweight.Bold;
hFont.Color=HSSFColor.White.Index;
hFont.FontHeightInPoints=18;
HSSFCellStyle hStyle=(HSSFCellStyle)wb.CreateCellStyle();
hStyle.SetFont(hFont);
hStyle.BorderBottom=BorderStyle.Medium;
hStyle.FillBackgroundColor=HSSFColor.Black.Index;
IRow headerRow=sheet.CreateRow(1);
int-cellCount=1;
foreach(colHeaders中的字符串str)
{
HSSFCell cell=(HSSFCell)headerRow.CreateCell(cellCount);
cell.SetCellValue(cHelp.CreateRichTextString((str));
cell.CellStyle=hStyle;
细胞计数+=1;
}
int rowCount=2;
foreach(data.Rows中的DataRow dr)
{
var row=sheet.CreateRow(rowCount);
对于(int i=1;i
附加调试器后,我注意到hStyle.FillBackgroundColor从不从0x0040更改,尽管黑色的索引是8
因此,基本上问题是:
- 为什么
不可修改HSSFCellStyle.FillBackgroundColor
FillBackgroundcolor
在未指定FillPattern
的情况下无法应用
i、 e
你的回答很有前景。问题在于背景。我按照你说的做了,得到了黑色的单元格,即使我把背景改成黄色。如果我将FillPattern更改为FillPattern.LeastDots,我只能看到黄色背景,这非常烦人!!还有人去吗clue@GregJF见:
hStyle = (HSSFCellStyle)workBook.CreateCellStyle();
hStyle.SetFont(xFont);
hStyle.BorderBottom = BorderStyle.Medium;
hStyle.FillForegroundColor = IndexedColors.Black.Index;
hStyle.FillPattern = FillPattern.SolidForeground;
