如何使用Apache POI为整行应用粗体文本样式？

How to make an entire excel row cells bold text using Apache POI?

如何使用Apache POI制作整个excel行单元格粗体文本?

E.g:
Column headings should be in bold. Instead of applying style for each and every cell of heading row, how can I apply some style to an entire row?

例如:列标题应以粗体显示。不是为标题行的每个单元格应用样式,而是如何将一些样式应用于整行?

This should work fine.

这应该工作正常。

    Workbook wb = new XSSFWorkbook("myWorkbook.xlsx");
    Row row=sheet.getRow(0);
    CellStyle style=null;

    XSSFFont defaultFont= wb.createFont();
    defaultFont.setFontHeightInPoints((short)10);
    defaultFont.setFontName("Arial");
    defaultFont.setColor(IndexedColors.BLACK.getIndex());
    defaultFont.setBold(false);
    defaultFont.setItalic(false);

    XSSFFont font= wb.createFont();
    font.setFontHeightInPoints((short)10);
    font.setFontName("Arial");
    font.setColor(IndexedColors.WHITE.getIndex());
    font.setBold(true);
    font.setItalic(false);

    style=row.getRowStyle();
    style.setFillBackgroundColor(IndexedColors.DARK_BLUE.getIndex());
    style.setFillPattern(CellStyle.SOLID_FOREGROUND);
    style.setAlignment(CellStyle.ALIGN_CENTER);
    style.setFont(font);

If you do not create defaultFont all your workbook will be using the other one as default.

如果您不创建defaultFont,则所有工作簿将默认使用另一个工作簿。

Please find below the easy way :

请在下面找到简单的方法:

XSSFCellStyle style = workbook.createCellStyle();
style.setBorderTop((short) 6); // double lines border
style.setBorderBottom((short) 1); // single line border
XSSFFont font = workbook.createFont();
font.setFontHeightInPoints((short) 15);
font.setBoldweight(XSSFFont.BOLDWEIGHT_BOLD);
style.setFont(font);                 

Row row = sheet.createRow(0);   
Cell cell0 = row.createCell(0);
cell0.setCellValue("Nav Value");
cell0.setCellStyle(style);  
for(int j = 0; j<=3; j++)
row.getCell(j).setCellStyle(style);

This work for me

这对我有用

I set style's font before and make rowheader normally then i set in loop for the style with font bolded on each cell of rowhead. Et voilà first row is bolded.

我之前设置了样式的字体并且正常地使用rowheader然后我在循环中设置了在行头的每个单元格上加粗字体的样式。 Etvoilà第一排是粗体。

HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet("FirstSheet");
HSSFRow rowhead = sheet.createRow(0); 
HSSFCellStyle style = wb.createCellStyle();
HSSFFont font = wb.createFont();
font.setFontName(HSSFFont.FONT_ARIAL);
font.setFontHeightInPoints((short)10);
font.setBold(true);
style.setFont(font);
rowhead.createCell(0).setCellValue("ID");
rowhead.createCell(1).setCellValue("First");
rowhead.createCell(2).setCellValue("Second");
rowhead.createCell(3).setCellValue("Third");
for(int j = 0; j<=3; j++)
rowhead.getCell(j).setCellStyle(style);

    Object[][] bookData = { { "col1", "col2", 3 }, { "col1", "col2", 3 }, { "col1", "col2", 3 },
            { "col1", "col2", 3 }, { "col1", "col2", 3 }, { "col1", "col2", 3 } };

    String[] headers = new String[] { "HEader 1", "HEader 2", "HEader 3" };

    int noOfColumns = headers.length;
    int rowCount = 0;

    Row rowZero = sheet.createRow(rowCount++);
    CellStyle style = workbook.createCellStyle();
    Font font = workbook.createFont();
    font.setBoldweight(Font.BOLDWEIGHT_BOLD);
    style.setFont(font);
    for (int col = 1; col <= noOfColumns; col++) {
        Cell cell = rowZero.createCell(col);
        cell.setCellValue(headers[col - 1]);
        cell.setCellStyle(style);
    }
