使用 Apache POI 将整行加粗 [英] Make the entire row bold using Apache POI

问题描述

我正在使用 Apache POI 的 HSSFWorkbook 将数据写入 Excel 电子表格.

I am using Apache POI's HSSFWorkbook to write data to Excel spreadsheets.

我想让整行加粗.有人可以建议怎么做吗?

I want to make an entire row bold. Can someone please suggest how to do it?

推荐答案

这样的事情是否适用于您现有的:

Would something like this work with what you have:

public static void makeRowBold(Workbook wb, Row row){
    CellStyle style = wb.createCellStyle();//Create style
    Font font = wb.createFont();//Create font
    font.setBold(true);//Make font bold
    style.setFont(font);//set it to bold

    for(int i = 0; i < row.getLastCellNum(); i++){//For each cell in the row 
        row.getCell(i).setCellStyle(style);//Set the style
    }
}

它基本上遍历传入的行中的每个单元格，将样式设置为粗体.应将整行设置为所需的样式.

It basically goes over each cell in the row passed in, setting the style to a bold one. Should result in the whole row being set to the desired style.

祝你好运！

一个更完整的例子:

public static void main(String[] args) {
    Path myFile = Paths.get(System.getProperty("user.home"), "Desktop", "tester.xlsx");

        try {
            XSSFWorkbook wb = new XSSFWorkbook(new FileInputStream(myFile.toFile()));
            XSSFSheet sheet = wb.getSheetAt(0);
            makeRowBold(wb, sheet.getRow(0));

            wb.write(new FileOutputStream(myFile.toFile()));
        } catch (IOException e) {
            e.printStackTrace();
        }
}


public static void makeRowBold(Workbook wb, Row row){
    CellStyle style = wb.createCellStyle();//Create style
    Font font = wb.createFont();//Create font
    font.setBold(true);//Make font bold
    style.setFont(font);//set it to bold

    for(int i = 0; i < row.getLastCellNum(); i++){//For each cell in the row 
        row.getCell(i).setCellStyle(style);//Set the sty;e
    }
}

这是在第 1 行数据的 xlsx 文件上测试的，结果文件之后有粗体数据.

This was tested on an xlsx file with data in row 1, the resulting file had bold data afterwards.
