Google Maps will not show with nested Div's?
Essentially the code wont show when I provide some sort of page container or any divs around the maps.

I'd hazard a guess that all the map canvas divs have the right width, but 0 height. You need to set a height on a wrapper of the map divs (such as the commented out <div id="table_for_maps" >) or set a non-percent height on the map divs (such as 300px).
You should use a tool like Firebug (Safari and Chrome come with built-in equivalents) to inspect the CSS yourself, to get more information about the problem.
Fixed my issue with API v3. Initial value supplied by Google was:
<div id="map_canvas" style="width:100%; height:100%"></div>
Just change the values to a pixel size such as:
<div id="map_canvas" style="width:850px,;height:600px"></div>
加载中,请稍侯......
