HTML table cells color wrong in reading mode

Steps to reproduce

Open Appimage (no matter, deb works the same) sandbox, new note, write:

<table>
<tr>
<th>Heading A</th>
<th>Heading B</th>
<th>Heading C</th>
</tr>
<tr>
<td class="bg-green">Cell A</td>
<td class="bg-green">Cell B</td>
<td class="bg-green">Cell C</td>
</tr>
<tr>
<td bgcolor="red">Cell D</td>
<td bgcolor="red">Cell E</td>
<td bgcolor="red">Cell F</td>
</tr>
</table>

No snippets used in this case, but CSS works the same.

Expected result

As I see in preview (edit) mode:

Actual result

At read mode, every even cell in every row is no colored:

Additional information

Before I installed obsidian v.1.5.3 and checked this bug, I’ve caught it in v.1.2.??

this is not a bug. You style is overwritten by another by another rule in the reader view. Moved to help.

Bug or feature, well, it turns out that the default CSS used by Obsidian is this line:

.markdown-rendered tbody tr > td:nth-child(2n+2) {
    background-color: var(--table-column-alt-background);
}

And this overrides your specification of bgcolor due to CSS specificity rules. So the default configuration for allowing for alternating column background color, is just on the edge related to the specificity, so non-even columns is ruled by bgcolor, and even column is governed by the rule above.

To ensure that your markup has high enough specificity, you could use:

<td style="background-color: red !important">Cell E</td>
