JS根据数字按顺序获取Excel表头的字母

    const numberToExcelColumn = (number) => {
        let letter = '';
        while (number > 0) {
            const remainder = (number - 1) % 26;
            letter = String.fromCharCode(remainder + 65) + letter;
            number = Math.floor((number - 1) / 26);
        }
        return letter.toUpperCase();
    }
    console.log(numberToExcelColumn(1)); // A
    console.log(numberToExcelColumn(2)); // B
    console.log(numberToExcelColumn(27)); // AA
    console.log(numberToExcelColumn(28)); // AB
