1. The horizontal-aligned straight table does display properly in AJAX.
2. This isn't too common, but if you define an expression as an image instead of text, the expression must always be an image for it to work in AJAX. You can not mix images and text in the same expression which the Plug-in handles fine.
Thanks for the post, i had added your items to the list, and during testing i've found that the horizontal straight table has been fixed (in my v10 SR1 anyway) I used the webview mode in the designer to test.
With the second item, do you have an example as i'm not sure exactly what you mean? it may also have been fixed in 10SR1.
