javascript - 默认添加导出自定义

Question

如何像这样默认添加导出按钮及其自定义功能

$.extend($.fn.dataTable.defaults, {
language: {
"loadingRecords": "Loading. Please wait...",
"info": "Showing <span class='startPage'>START</span> to <span class='endPage'>END</span> of <span class='totalPage'>TOTAL</span> entries",
"lengthMenu": "Showing MENU entries"
},
});

只需使用 buttons 文字进行扩展:

$.extend( $.fn.dataTable.defaults, {
  buttons: [{ 
     extend: 'pdfHtml5',
     customize: function(doc) {
        doc.defaultStyle.fontSize = 40; 
     }   
   }]  
});
