What is the proper way to include 'rowspan' specific CSS within an HTML table?

Question

What is the proper way to include 'rowspan' specific CSS within an HTML table?

I have an HTML table with rowspans in it:

table tr,
td {
  border: 1px solid black;
}
tr:nth-child(1) {
  background-color: red;
}
tr:nth-child(2) {
  background-color: blue;
}

<table>
  <tr>
    <td rowspan=2>Section 1</td>
    <td>Data 1a</td>
  </tr>
  <tr>
    <td>Data 1b</td>
  </tr>
  <tr>
    <td rowspan=3>Section 2</td>
    <td>Data 2a</td>
  </tr>
  <tr>
    <td>Data 2b</td>
  </tr>
  <tr>
    <td>Data 2C</td>
  </tr>

I am trying to find a simple CSS solution using nth-child to apply styling, such as background colors, to a group of rows within a "Section" that is defined by row spans.

The current CSS only styles individual table rows based on their position, but I want to target and style multiple rows based on the number of rows spanned by a cell.

In this example, I would like to:

Make Section 1, Data 1a, and Data 1b appear in red
Style Section 2, Data 2a, Data 2b, and Data 2c with a blue color

If you have any suggestions for achieving this using simple HTML/CSS without relying on JavaScript, please let me know!

The solution that I found to be effective (thanks to @RobG's suggestion) is organizing the group rows into segments using <tbody>. This way, I can easily target each tbody element.

Below is the updated example that demonstrates this concept:

table tr,
td {
  border: 1px solid black;
}
tbody:nth-child(1) {
  background-color: red;
}
tbody:nth-child(2) {
  background-color: blue;
}

<table>
  <tbody>
  <tr>
    <td rowspan=2>Section 1</td>
    <td>Data 1a</td>
  </tr>
  <tr>
    <td>Data 1b</td>
  </tr>
  </tbody>
  <tbody>
  <tr>
    <td rowspan=3>Section 2</td>
    <td>Data 2a</td>
  </tr>
  <tr>
    <td>Data 2b</td>
  </tr>
  <tr>
    <td>Data 2C</td>
  </tr>
  </tbody>

If you opt for simple classes or IDs for your table rows and cells, managing them becomes a breeze. I included the header cells in this example, but even if you switch them back to regular cells, the outcome remains consistent. By assigning appropriate class names to each row, it becomes easier to target them, allowing for seamless addition of <td> tags to red or blue rows which will automatically inherit the correct color, eliminating the need to determine their position.

table tr,
td, th {
  border: 1px solid black;
}
tr.red > td, tr.red > th {
  background-color: red;
}
tr.blue > td, tr.blue > th {
  background-color: blue;
}

<table>
  <tr class="red">
    <th rowspan=2>Section 1</th>
    <td>Data 1a</td>
  </tr>
  
  <tr class="red">
    <td>Data 1b</td>
  </tr>
  
  <tr class="blue">
    <th rowspan=3>Section 2</th>
    <td>Data 2a</td>
  </tr>
  
  <tr class="blue">
    <td>Data 2b</td>
  </tr>
  
  <tr class="blue">
    <td>Data 2C</td>
  </tr>
  
</table>

If you prefer not to modify your HTML code, here is a straightforward solution:

tr, td {
    border: 1px solid black;
}

tr, tr + tr  {
    background-color: red;
}

tr + tr + tr {
    background-color: blue;
}

<table>
   <tr>
       <td rowspan=2>Section 1</td>
       <td>Data 1a</td>
   </tr>
   <tr>
       <td>Data 1b</td>
   </tr>
   <tr>
       <td rowspan=3>Section 2</td>
       <td>Data 2a</td>
   </tr>
     <tr>
       <td>Data 2b</td>
   </tr>
   <tr>

tbody + tbody tr {
background-color: blue;
}

<table>
   <tbody>
