使用 Javascript 对象作为数据馈送合并两个 HTML 表？

Question

我将有多个数组数组，我想从数组中创建对象，然后将其合并到一个表中。我已经这样做了，但是我需要帮助使用该对象来制作一张更大的桌子吗？

如果键存在于一个对象中但不存在于其他对象中，则该键不存在的对象的值可以为空。我可以制作多个不同的表格，但是如何合并它们以使表格变大？

var data  =[["default_PROJECT","Allow","Connect","Allow","AddComment","Allow","Write",
"Allow","ViewComments","Allow","ExportData","Allow","ExportImage","Allow","ViewUnderlyingData","Allow","Read","Allow","ShareView","Allow","Filter"],
["Allow","ExportImage","Allow","Write","Allow","ViewComments",
"Allow","ShareView","Allow","Filter","Allow","ExportData","Allow","Connect","Allow",
"Read","Allow","ViewUnderlyingData","Allow","AddComment","Allow","ViewComments","Deny","ExportData","Allow",
"AddComment","Deny","Write","Allow","Read","Deny","ExportXml","Deny","ShareView","Allow","Connect","Allow","ChangeHierarchy","Allow",
"WebAuthoring","Deny","ViewUnderlyingData","Deny","Filter","Deny","ExportImage"]];
  			 var result = [];
		 for(var i = 0, len = data.length; i < len; i++) {
		   var list = data[i];
		   
		   result[i] = { name: list[0] };

		  for (var j = list.length - 1; j >= 1; j = j - 2) {
		     var key = list[j];
		     var value = list[j - 1];
		     if( result[i][key] !== "Deny" ) {
		         result[i][key] = value;
		     }
		 }
		 }
		 console.log(result);
		 var resultElement = document.getElementById('result1');
		 var tpl = '';
		 for(var t = 0, tLen = result.length; t < tLen; t++) {
		   var item = result[t];
		   
		   tpl+= '<table align=center style="width:25%;">' +
		     '<thead>' +
		       '<tr><td colspan="2">Project: ' + item.name + '</td></tr>' +
		       '<tr><th>Permission</th><th>Value</th></tr>' +
		       '</thead>' +
		     '<tbody>'
		   ;
		   
		   for(var key in item) {
		     if(!item.hasOwnProperty(key) || key === 'name') { continue; }
		     if(item[key] == "Allow"){
			     tpl += '<tr style="background-color:greenyellow;"><td>'+ key +'</td><td>'+ item[key] +'</td></tr>';   
		     }
		     else{
			     tpl += '<tr style="background-color:red;"><td>'+ key +'</td><td>'+ item[key] +'</td></tr>';   
		     }
		   }
		 }
		 resultElement.innerHTML = tpl;

table { text-align: left; width: 100%; margin-bottom: 50px; border-collapse: collapse;}
td, th { width: 50%; border: 1px solid black; line-height: 1; padding:2px 10px;}
[colspan="2"] { color: blue; font-weight: bolder;text-transform: uppercase; text-align: center;}

<div id="result1"></div>

这会合并两个表。
