Hi,
please try this modified CSS:
.tablepress-id-3 .highlight-y {
background-color: #fcfc03 !important;
}
In the CSS, the letter needs to be lower-case.
In addition, you might want to add another parameter to the Shortcode to restrict the search to the fourth column (otherwise every Y
in the table will be highlighted):
highlight_columns=4
For the second question: Unfortunately, there’s not direct Extension for that. You can search tables on the “List of Tables”, to find all tables that contain a search term. Then, on each table’s “Edit” screen, you can use the browser search function to find the search term (hit Ctrl+F (Windows) or Cmd+F (Mac)). For mass search/replace, you could export the table to a CSV file, and open that in a normal text editor. Those usually have a search/replace feature. Then, just import the modified CSV file again, choosing to replace the existing table.
Regards,
Tobias
