Header colors multiple tables

I have successfully changed the header color and fonts one of several tables I use. Table is at bottom of https://nehs.4j.lane.edu/?page_id=447

I used this:
.wp-table-reloaded-id-9 th, .wp-table-reloaded-id-9 .sorting {
background-color: #cc0000!important;
color: #ffffff!important;
padding: 3px 3px 1px 3px;
line-height: 16px;
border-style: none;
border-width: 0px;
}

I haven’t been able to change the color in other table headers. I’ve tried copying the same code and changing the id, and I’ve tried putting a string of tables together like this:
.wp-table-reloaded-id-9 th, .wp-table-reloaded-id-9 .sorting, .wp-table-reloaded-id-21 th, .wp-table-reloaded-id-21 .sorting {
background-color: #cc0000!important;
color: #ffffff!important;
padding: 3px 3px 1px 3px;
line-height: 16px;
border-style: none;
border-width: 0px;
}

I hope it’s not something in the theme css causing this, I don’t have privileges to mess with the theme.

Here’s the page of the other table I am trying to change. https://nehs.4j.lane.edu/?page_id=1332
