Question

我使用jspdf将html表导出为pdf。我正在尝试格式化表格。我能够调整边距。我想将几列表格右对齐，少数左对齐。在表格中，我希望第一列与左对齐，最后一列与右对齐。

      <div>
     <button onclick="demoFromHTML()" class="button">SAvePDF</button></p></div></div>
     </div>

这是javascript文件

       <script>
      $(document).ready(function() {
       demoFromHTML();
      });

     function demoFromHTML() {
     var pdf = new jsPDF('p', 'pt', 'letter')
     , source = $('#tblSaveAsPdf')[0]
     ,  specialElementHandlers = {
     '#bypassme': function(element, renderer){
      return true
       }
      }

     margins = {
      top: 80,
      bottom: 60,
      left: 40,
      width: 522
      };

  pdf.fromHTML(
     source // HTML string or DOM elem ref.
     , margins.left // x coord
     , margins.top // y coord
     , {
     'width': margins.width // max width of content on PDF
     , 'elementHandlers': specialElementHandlers
     },
    function (dispose) {   
        pdf.save('Test.pdf');
      },
    margins

     )
   }
   </script>

好的解决方案是将表拆分为不同的表，并将其与jspdf.plugin.htmltable.js对齐。希望它可以帮到你

Answer 2

更好的解决方案是修改jspdf.plugin.html table.js以切换cell.align。并在html表格的单元格中添加对齐。

switch (options.align || cell.align) {
     case '-webkit-right':
     case 'right':
       if (!(txt instanceof Array)) {
           txt = [txt];
       }
       for (i = 0; i < txt.length; i++) {
         var textSize = this.getStringUnitWidth(txt[i]) * this.internal.getFontSize();
         this.text(txt[i], cursor.x + cell_widths[x] - textSize - padding, cursor.y + this.internal.getLineHeight()*(i+1));
        }
   break;

使用jspdf对齐表中列的文本
