示例代码：

var rowColOrder = [

//row是行，col是列，order是拼接顺序

    { row: 3, col: 1, order: 2 }, 

    { row: 5, col: 1, order: 1 },  

    { row: 6, col: 1, order: 3 },  

{ row: 7, col: 1, order: 5 },

];

    const div = document.getElementById(myTable);  

    const resultArray = [];  

    rows = div.getElementsByTagName('tr');

    rowColOrder.forEach(item => {  

        const { row, col, order } = item; 

        if (row < rows.length && col < rows[row].cells.length) {  

            let cellValue = rows[row].cells[col].innerText; 

cellValue=cellValue.replace(/\\n|\\t|\\r|\n|\t|\r/g, ''); //去除转义字符

cellValue=cellValue.replace(/<[^>]*>/g, '');//去掉html

if (cellValue!=""&&cellValue!=null){

resultArray.push({ value: cellValue, order: order }); // 保存值和顺序 

}

        }  

    });  

    // 按 order 排序  

    resultArray.sort((a, b) => a.order - b.order);  

    const concatenatedResult = resultArray.map(item => item.value).join("*");  

    return concatenatedResult;  

}
