Responsive Table Break - html

Question

I have a website that is connected to a database. The website has a table that pulls out the values from the database. I want this table to be responsive. I have almost got it to work except one part. Everything is showing and working except for the titles(Band Name, City, Role, Style, SKill). They wont show. I think it has something to do with the last CSS code (content attribute). If someone has experience or can help out, I would highly appreciate it! Take a look at the photo to to see what I mean

I got the help of a friend to answer this question
The code that had to be changed is:
HTML:
<td data-label="Band Name"th:text="${band.bandName}">Band Name</td>
And
CSS:
.table td::before{
content: attr(data-label);
