Answer 1

You could simply specify the width for the th and td elements, say 50%.
table, th, td {
border: 1px solid black;
}
table th, table td {
width: 50%;
}
table th {
text-align: left;
}
<table style="width:100%" cellpadding="10px" cellspacing="1px" padding="20px">
<tr>
<th>Month</th>
<td>Savings</td>
</tr>
<tr>
<th>January</th>
<td >$100</td>
</tr>
<tr>
<th>February</th>
<td >$80</td>
</tr>
</table>
<table style="width:100%" cellpadding="10px" cellspacing="1px" padding="20px">
<tr>
<th>Monthasnsandf</th>
<td>Savings</td>
</tr>
<tr>
<th>Januarydfsadfas</th>
<td >$100</td>
</tr>
<tr>
<th>Februarydfsadfsafa</th>
<td >$80</td>
</tr>
</table>

Answer 2

what I did is put the two tables in another table which has 2 rows to perfectly match vertical alignment
table, th, td {
border: 1px solid black;
}
table th, table td {
width: 50%;
}
<table>
<tr>
<td>
<table style="width:100%">
<tr>
<th>Month</th>
<td>Savings</td>
</tr>
<tr>
<th>January</th>
<td >$100</td>
</tr>
<tr>
<th>February</th>
<td >$80</td>
</tr>
</table>
</td>
</tr>
<tr>
<td>
<table style="width:100%">
<tr>
<th>Monthasnsandf</th>
<td>Savings</td>
</tr>
<tr>
<th>Januarydfsadfas</th>
<td >$100</td>
</tr>
<tr>
<th>Februarydfsadfsafa</th>
<td >$80</td>
</tr>
</table>
</td>
</tr>
</table>
I assume this is what you expect!
