HTML Hide Table rows - css

Question

So I am trying to add an incrementing number to the first cell of a HTML table. Which I have done using examples found in this forum. What I want to do next is hide any row that only contains the number in the first cell. The only real option I have available is css but I am unsure if it is possible. The code I have so far is
table {
border-collapse: collapse;
counter-reset: rowNumber;
}
table tr:not(:first-child) {
counter-increment: rowNumber;
}
table td > *:empty {
display: none;
}
tr > td:empty {
background-color: yellow;
}
table tr td:first-child::before {
content: counter(rowNumber);
min-width: 1em;
margin-right: 0.5em;
}
<table border="1px" empty-cells:hide;>
<tr>
<td></td>
<td></td>
</tr>
<tr>
<td></td>
<td>Test</td>
</tr>
<tr>
<td></td>
<td>Test</td>
</tr>
<tr>
<td></td>
<td>Test</td>
</tr>
</table>

Here I'm hiding all sibling TR elements if the first TR is empty.
Using CSS, you can not control parent as there are no parent selectors.
Here is the code -
table {
border-collapse: collapse;
}
table tr:not(:first-child) {
counter-increment: rowNumber;
}
tr > td:first-child:empty,
tr > td:first-child:empty ~ td {
display: none;
}
table tr td:first-child::before {
content: counter(rowNumber);
min-width: 1em;
margin-right: 0.5em;
}
<table border="1px" empty-cells:hide;>
<tr>
<td>Has Text</td>
<td>Test</td>
</tr>
<tr>
<td></td>
<td>Test</td>
</tr>
<tr>
<td>Has Text</td>
<td>Test</td>
</tr>
<tr>
<td></td>
<td>Test</td>
</tr>
</table>

Building on #CharanKumar answer, what you could do is remove the first column, and apply the numbering to the row with text. You could then add some padding and a border-right to simulate a separate cell.
It would look like below:
table {
border-collapse: collapse;
}
table tr:not(:first-child) {
counter-increment: rowNumber;
}
tr > td:first-child:empty,
tr > td:first-child:empty ~ td {
display: none;
}
table tr td:first-child::before {
content: counter(rowNumber);
min-width: 1em;
margin-right: 0.5em;
border-right: 1px solid black;
padding: 1px 5px 1px 1px;
}
<table border="1px" empty-cells:hide;>
<tr>
<td></td>
</tr>
<tr>
<td>Test</td>
</tr>
<tr>
<td>Test</td>
</tr>
<tr>
<td>Test</td>
</tr>
</table>
