 * Hi there!
 * Google PageSpeed indicates that the render-blocking javascript of tablepress 
   should be removed. I use Autoptimize. Can this be removed?
 * Warm regards,

 * Hi,
 * thanks for your post, and sorry for the trouble.
 * Unfortunately, I don’t know how to further optimize this, sorry.
 * Also, do you mean JavaScript or CSS?
 * Regards,

 * Hi Tobias,
 * Thanks for your quick response. Google literally says:
 * “Resources are blocking the first paint of your page. Consider delivering critical
   JS/CSS inline and deferring all non-critical JS/styles. Learn more.
    WordPress
   There are a number of WordPress plugins that can help you inline critical assets
   or defer less important resources. Beware that optimizations provided by these
   plugins may break features of your theme or plugins, so you will likely need 
   to make code changes.”
 * Warm regards,
    Siebren

 * Hi guys;
    Quick feedback from me; `wp-content/plugins/tablepress-responsive-tables/
   css/tablepress-responsive-flip.min.css` is not aggregated by AO because it is
   in “IE conditionals” which AO always leaves in place because AO cannot cater 
   for CSS that is targetting specific browsers (versions of IE). In this case though
   the IE conditional tells IE not to use the stylesheet at all, which makes this
   a special case. Not sure if you can fix this another way Tobias?

 * Hi,
 * I’m not sure… The CSS file is necessary for all browsers except IE…
    Now, IE 
   is being phased out in favor of Edge, which will even use Chromium as a foundation,
   so in the future, this might indeed no longer be necessary.

 * This talks about the CSS issue, but in order for tablepress to function correctly,
   I have to exclude jquery from AO optimization. Is there anything that can be 
   tweaked in the js that would allow me not to need to exclude jquery? I did figure
   out that if I enable the “Let Autoptimize also extract JS from the HTML. Warning:
   this can make Autoptimize’s cache size grow quickly, so only enable this if you
   know what you’re doing.” in AO, tablepress works without having to exclude jquery
   from AO optimization, but then my AO cache grows quickly as stated and causes
   other issues for me.

 * Hi,
 * I’m really sorry, but I’m not aware of other solution approaches here 🙁
 * Regards,
