How to use nth-child for styling with a table with rowspan?

Answer 1

What seems to work for me is to put a td in the row below with display:none

<table>
   <tr>
      <td rowspan="2">2 rows</td>
      <td>1 row</td>
   </tr>
   <tr>
      <td style="display:none"></td>
      <td>1 row</td>
   </tr>
</table>

Answer 2

I had a similar issue and I just overrode the row background with backgrounds on the TD's inside of them. Depending on your desired outcome, this may work for you too?

tr:nth-child(odd) {
    background: #DDE;
}
tr:nth-child(odd) td[rowspan] {
    background: #FFF;
}

Of course you can override other rows like headers, etc with a class or th.

Try to separate table by tbody, something like:

tbody tr:nth-child(odd){
  background: #00FFFF;
}
tbody tr:nth-child(even){
  background: #FF0000;
}

tbody:nth-child(odd)  td[rowspan]{
  background: #00FFFF;
}
tbody:nth-child(even)  td[rowspan]{
  background: #FF0000;
}  

<table>
<tbody>
<tr>
	<td rowspan="4">...</td>
	<td>...</td>
	<td>...</td>
	<td rowspan="4">...</td>
	<td>...</td>
</tr>
<tr>
	<td>...</td>
	<td>...</td>
	<td>...</td>
</tr>
<tr>
	<td>...</td>
	<td>...</td>
	<td>...</td>
</tr>
<tr>
	<td>...</td>
	<td>...</td>
    <td>...</td>
</tr>
</tbody>
<tbody>    
<tr>
	<td rowspan="3">...</td>
	<td>...</td>
	<td>...</td>
	<td rowspan="3">...</td>
	<td>...</td>
</tr>
<tr>
	<td>...</td>
	<td>...</td>
	<td>...</td>
</tr>
<tr>
	<td>...</td>
	<td>...</td>
	<td>...</td>
</tr>
</tbody>
</table>
    
  

Answer 4

I used a combination of previous answer to add tr's with display=none programatically:

HTML

  <table>
  <tr>
    <td>A</td>
    <td>B</td> 
    <td>C</td>
  </tr>
  <tr>
    <td rowspan=2>1</td>
    <td rowspan=2>2</td>
     <td>sub C 1</td>
  </tr>
  <tr>
    <td>sub C 2</td> 
  </tr>
  <tr>
    <td>3</td>
    <td>4</td>
    <td>5</td>
  </tr>
  <tr>
    <td>6</td>
    <td>7</td>
    <td>8</td>
  </tr>
</table>

CSS

table tr:nth-child(2n) {
  background-color: #F8ECE0;
}

JQUERY

$( "<tr style='display:none'></tr>" ).insertAfter('tbody tr:has(td[rowspan])');

See the JSfiddle.

Answer 5

Unfortunately, there's no way to do this with :nth-child() alone, or by using CSS selectors alone for that matter. This has to do with the nature of :nth-child() which selects purely based on an element being the nth child of its parent, as well as with CSS's lack of a parent selector (you can't select a tr only if it doesn't contain a td[rowspan], for example).

---

jQuery does have the :has() selector that CSS lacks, though, which you can use in conjunction with :even (not :odd as it's 0-indexed versus :nth-child()'s 1-index) for filtering as an alternative to CSS:

$('tr:not(:has(td[rowspan])):even')

Answer 6

You can do this using only CSS if you're willing to add some additional markup. Wrap every "group" of rows in a <tbody> tag. Then add a background color to every odd tbody.

tbody:nth-child(odd) {
  background-color: yellow;
}

<table>
  <tbody>
    <tr>
      <td>tr 1</td>
      <td>...</td>
      <td>...</td>
    </tr>
  </tbody>
  <tbody>
    <tr>
      <td rowspan="2">tr 2+3</td>
      <td>...</td>
      <td>...</td>
    </tr>
    <tr>
      <td>...</td>
      <td>...</td>
    </tr>
  </tbody>
  <tbody>
    <tr>
      <td>tr 4</td>
      <td>...</td>
      <td>...</td>
    </tr>
  </tbody>
  <tbody>
    <tr>
      <td>tr 5</td>
      <td>...</td>
      <td>...</td>
    </tr>
  </tbody>
  <tbody>
    <tr>
      <td>tr 6</td>
      <td>...</td>
      <td>...</td>
    </tr>
  </tbody>
  <tbody>
    <tr>
      <td>tr 7</td>
      <td>...</td>
      <td>...</td>
    </tr>
  </tbody>
  <tbody>
    <tr>
      <td>tr 8</td>
      <td>...</td>
      <td>...</td>
    </tr>
  </tbody>
  <tbody>
    <tr>
      <td>tr 9</td>
      <td>...</td>
      <td>...</td>
    </tr>
  </tbody>
  <tbody>
    <tr>
      <td>tr 10</td>
      <td>...</td>
      <td>...</td>
    </tr>
  </tbody>
</table>
