É possível mudar o Rótulo das Linhas?

You can do it with some CSS code. You should inject the following piece of code per row:

th#row_1:after {

 content: "Custom text"; /*Replace this with your text for this row*/

 font-size: 16px;

}

th#row_1{

 font-size: 0;

}

You would only need to change the number on the identifier, so for the second row use "th#row_2:after " and "th#row_2 ".

In order to inject the CSS code, you can follow this guide:
