 Replying to [comment:6 hbhalodia]:

 `sanitize_html_class `
 https://developer.wordpress.org/reference/functions/sanitize_html_class/
 function

 Thanks for the PR! However, as noted above, the `$columns` variable goes
 through `absint()` and is not user-editable, so it does not currently
 require sanitization.

 It is also worth noting that per the
 [https://developer.wordpress.org/apis/security/#h-guiding-principles
 security guiding principles], sanitizing should be done early and escaping
 should be as late as possible, so for the output itself, `esc_attr()`
 would be the correct function to use.
