如何使用 Apache POI 使整个 Excel 行单元格变为粗体文本?

例如:
列标题应为粗体。我如何将某些样式应用于整行,而不是为标题行的每个单元格应用样式?

这应该可以正常工作。

    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);

如果您不创建defaultFont所有工作簿,则默认使用另一个工作簿。

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);

这对我有用

我之前设置了样式的字体并正常制作了行头,然后我在循环中设置了样式,在行头的每个单元格上用粗体显示字体。Et voilà 第一行是粗体的。

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);

这对我有用

    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);
    }

一个工作,完成和简单的例子:

package io.github.baijifeilong.excel;

import lombok.SneakyThrows;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

import java.io.FileOutputStream;

public class ExcelBoldTextDemo {

    @SneakyThrows
    public static void main(String[] args) {

        new XSSFWorkbook() {{
            XSSFRow row = createSheet().createRow(0);
            row.setRowStyle(createCellStyle());
            row.getRowStyle().getFont().setBold(true);
            row.createCell(0).setCellValue("Alpha");
            row.createCell(1).setCellValue("Beta");
            row.createCell(2).setCellValue("Gamma");
        }}.write(new FileOutputStream("demo.xlsx"));
    }
}
