table-plugin: WAI input stays when you click on it and table floating menu stays when a row/colum is selected.

WAI input disappeared because of a selection issue with mouse-up event. Mouse-up event was stopped if a cell is selected. Mouseup event should not be stopped because it is used in the jquery.aloha.js file (jquery.aloha.js:207) for initializing the selection.

Selecting a row/column in table did throw a javascript exception regarding the selection range (rangy-core issue). This error is caught for IE7 and IE8, but not for document mode IE7. Catching the error in case the document mode is less or equal than 8 solves the issue.
