Recently, a project management module was developed, using the extjs tree component and the editorgrid component. The background generates JSON data through a proxy to parse the two components. The function is implemented, but some IE6 cannot correctly display the data, so I am depressed for a while. First, upgrade to IE7. Later found that Domino engine is not UT
