如何使用jspdf、jspdf-autotable适合宽表

Question

我正在使用jspdf和jspdf-autotable插件来创建一个非常宽的表的pdf，有没有一种方法可以自动调整表/列数据以适应任何页面大小？

我尝试了下面的代码，使用overflow：'linebreak‘，但它在单词的中间而不是空白处将单词换开

​

function demoPDF() {
  var pdfsize = 'a0';
  var pdf = new jsPDF('l', 'pt', pdfsize);

  var res = pdf.autoTableHtmlToJson(document.getElementById("rpt_tbl"));
  pdf.autoTable(res.columns, res.data, {
    startY: 60,
    tableWidth: 'auto',
    columnWidth: 'auto',
    styles: {
      overflow: 'linebreak'
    }
  });

  pdf.save(pdfsize + ".pdf");
};

我不完全确定我是否理解了你的问题，但是如果你想让一些列简单地换行，而另一些列换行，你可以这样做。

​

function demoPDF() {
  var pdfsize = 'a0';
  var pdf = new jsPDF('l', 'pt', pdfsize);

  pdf.autoTable({
    html: '#table',
    startY: 60,
    styles: {
      fontSize: 50,
      cellWidth: 'wrap'
    },
    columnStyles: {
      1: {columnWidth: 'auto'}
    }
  });

  pdf.save(pdfsize + ".pdf");
};

demoPDF();
