如何使用JAVA设置Excel标题文本的字体颜色

import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("Sheet1");

Row titleRow = sheet.createRow(0);
Cell titleCell = titleRow.createCell(0);
titleCell.setCellValue("标题文本");

Font font = workbook.createFont();
font.setColor(IndexedColors.RED.getIndex()); // 设置字体颜色为红色

CellStyle style = workbook.createCellStyle();
style.setFont(font);

titleCell.setCellStyle(style);

try (FileOutputStream outputStream = new FileOutputStream("path/to/excel.xlsx")) {
    workbook.write(outputStream);
}
