这是我的表查找

This is my table looking

这是pdf输出

我试图添加一个表

$('#cmd').click(function () {

        var table = tableToJson($('#StudentInfoListTable').get(0))
        var doc = new jsPDF('p', pt, 'a1', true);
        doc.cellInitialize();
        $.each(table, function (i, row){
            console.debug(row);
            $.each(row, function (j, cell){
                doc.cell(10, 50,120, 50, cell, i);  // 2nd parameter=top margin,1st=left margin 3rd=row cell width 4th=Row height
            })
        })


        doc.save('sample-file.pdf');
    });

以下是函数

function tableToJson(table) {
    var data = [];

    // first row needs to be headers
    var headers = [];
    for (var i=0; i<table.rows[0].cells.length; i++) {
        headers[i] = table.rows[0].cells[i].innerHTML.toLowerCase().replace(/ /gi,'');
    }


    // go through cells
    for (var i=0; i<table.rows.length; i++) {

        var tableRow = table.rows[i];
        var rowData = {};

        for (var j=0; j<tableRow.cells.length; j++) {

            rowData[ headers[j] ] = tableRow.cells[j].innerHTML;

        }

        data.push(rowData);
    }       

    return data;
}

让我看到这个输出后哭泣！
