In HTML editor I have code like: <table class="white">sth...</table> and
<div style="float: left; width: 35%;"> sth... </div>. If I switch between HTML and Visual editor, it's ok. Problem is, if I select whole table in Visual editor and want to copy this table again, under the old one. Table is copying, but style is missing ~ second table isn't same as the parent. I tried many WISIWYG editors, with the same reslut - always missing styles. I'm using default WP theme - TwentyEleven.
