hi, Need help with a simple problem! (see image) which has the following criteria: 1) table centred at middle point not left side (as resizing viewport effects it)2) table fixed to top viewport (scroll below with table fixed to top in viewport always)3) and needs z-index function It may sound simple but I'm being googled it for days now and looked over many forums.Code can be in html css or js, but please post a full working example as I'm new to coding.Thanks
