以pdf格式下载的表格无法在jspdf中使用

Question

我正在尝试使用jspdf在pdf中获取表格（html）的图像。

我指的是url / post。 http://embed.plnkr.co/scZ5u0/

下面是代码：

var quotes = document.getElementById('__xmlview0--captureTable');

html2canvas(quotes, {
        onrendered: function (canvas) {



            for (var i = 0; i <= quotes.clientHeight / 980; i++) {
                //! This is all just html2canvas stuff
                var srcImg = canvas;
                var sX = 0;
                var sY = 1100 * i; // start 1100 pixels down for every new page
                var sWidth = 900;
                var sHeight = 1100;
                var dX = 0;
                var dY = 0;
                var dWidth = 900;
                var dHeight = 1100;

                window.onePageCanvas = document.createElement("canvas");
                onePageCanvas.setAttribute('width', 900);
                onePageCanvas.setAttribute('height', 1100);
                var ctx = onePageCanvas.getContext('2d');
                // details on this usage of this function: 
                // https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API/Tutorial/Using_images#Slicing
                ctx.drawImage(srcImg, sX, sY, sWidth, sHeight, dX, dY, dWidth, dHeight);

                // document.body.appendChild(canvas);
                var canvasDataURL = onePageCanvas.toDataURL("image/png", 1.0);

                var width = onePageCanvas.width;
                var height = onePageCanvas.clientHeight;

                //! If we're on anything other than the first page,
                // add another page
                if (i > 0) {
                    pdf.addPage(612, 791); //8.5" x 11" in pts (in*72)
                }
                //! now we declare that we're working on that page
                pdf.setPage(i + 1);
                //! now we add content to that page!
                pdf.addImage(canvasDataURL, 'PNG', 20, 40, (width * .62), (height * .62));

            }
        }
    })

pdf.save('capture.pdf');

仅下载空白pdf文件。 任何对此的建议，将不胜感激。
