If I wanted to develop a website using Amiga, and particularly AmigaOS4+ I'd use AAMP with PhpMyAdmin installed, Codebench (looking forward to the HTML/CSS/PHP/FTP functionality!) and AmiFTP.
Suppose MorphOS users can use Scribble and an FTP client, not sure an AMP stack is available yet for MorphOS - feel free to correct me as my knowledge of MorphOS is next to non-existent.
Ofc lets not forget you could use a CMS-instead e.g. Drupal, WordPress and Joomla to name, but a few. Drupal and WordPress are great in both a local install (yes I've tried them) and remote side - just a little on the slow side- especially WordPress.
Personally, I must admit I do use Dreamweaver, however I completely ignore the WYSIWYG side of it - I use a separate commercial product instead for building CSS. Dreamweaver is useful for a) syntax highlighting and b) the help-as-you-type functionality. From time-to-time I like to fallback to TextWrangler and Cyberduck as they are no-where near as resource-heavy.
RE: Table usage. Another reason to avoid tables is for SEO reasons, Google in particular.
