使用Javascript简化HTML表

Question

我想使用PHP数组创建看起来更简单的表，并且需要使用Javascript的帮助。 最初我想像第一个表一样创建表，但是由于PHP数组的提供者的限制，我遇到了问题。

<style>
table {
    font-family: arial, sans-serif;
    border-collapse: collapse;
    width: 100%;
}

td, th {
    border: 1px solid #dddddd;
    text-align: left;
    padding: 8px;
}


</style>
<table>
	<thead>
		<tr>
			<td rowspan="3">Scope/Coverage</td>
			<td colspan="5">Economically Active</td>
			<td rowspan="3">Percentage of Working to Economically Active</td>
			<td colspan="4">Not Economically Active</td>
			<td rowspan="3">Total</td>
			<td rowspan="3">Percentage of Economically Active to Working Age Population</td>
		</tr>
		<tr>
			<td rowspan="2">Working</td>
			<td colspan="3">Unemployment</td>
			<td rowspan="2">Total of Economically Active</td>
			<td rowspan="2">Attending School</td>
			<td rowspan="2">Housekeeping</td>
			<td rowspan="2">Total of Not Economically Active</td>

		</tr>
		<tr>
			<td>Ever Worked</td>
			<td>Never Worked</td>
			<td>Total</td>
		</tr>
	</thead>
</table>

由于开发人员的限制，我得到了一个特定的PHP数组，并按如下方式打印：

<style>
table {
    font-family: arial, sans-serif;
    border-collapse: collapse;
    width: 100%;
}

td, th {
    border: 1px solid #dddddd;
    text-align: left;
    padding: 8px;
}


</style>
<table>
  	<thead>
  		<tr>
  			<td rowspan="3">Scope/Coverage</td>
        <td>Economically Active</td><td>Economically Active</td><td>Economically Active</td><td>Economically Active</td><td>Economically Active</td><td></td><td>Not Economically Active</td><td>Not Economically Active</td><td>Not Economically Active</td><td>Not Economically Active</td><td></td><td></td></tr><tr><td></td><td>Unemployment</td><td>Unemployment</td><td>Unemployment</td><td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td></tr><tr><td>Working</td><td>Ever Worked</td><td>Never Worked</td><td>Total</td><td>Total of Economically Active</td><td>Percentage of Working to Economically Active</td><td>Attending School</td><td>Housekeeping</td><td>Others</td><td>Total of Not Economically Active</td><td>Total</td><td>Percentage of Economically Active to Working Age Population</td></tr><tr>  		</tr>
  	</thead>
  </table>

如果您能帮助我解决这个问题，那就太好了
