js结构封装，怎么把一个一维数组和二维数组，封装成另一种结构呢，代码如下

var colOne = [[
        'account',
        'accountName'
    ],
    [
        'wxHead',
        'wxHeadImage'
    ],
    [
        'name',
        'username',
        'abc'
    ]];

var colTwo = ['field', 'title','formatter'];

const transFun = (colOne, colTwo) => colOne.map(n => {
    let o = {};
​
    n.forEach((m, j) => o[colTwo[j]] = m);
​
    return o;
});

function transM(colOne,colTwo){
    var cols=[];
    for(var i=0;i<colOne.length;i++){
        var tmp={};
        var tmpColOne=colOne[i];
        var len=tmpColOne.length<=colTwo.length?tmpColOne.length:colTwo.length;
        for(var k=0;k<len;k++){
            if(colOne[i][k]){//判断是否为空值
                tmp[colTwo[k]]=colOne[i][k];
            }
        }
        cols[i]=tmp;
    }
    return cols;
}
