    Default Large number of columns in ExtJS grid

    How many columns can an Ext JS grid handle?

    Can it reasonably handle 1,000 columns?

    Has there been any progress since this blog* was posted?

    * this has been done by someone trying to show that their grid is a lot better at handling a large number of columns

    Looks like their grid is rendering columns lazily; I don't believe we do that in our grid.

    Personally I wouldn't want to do that in my apps because that totally wrecks accessibility, among other things.

    http://www.enterprisesheet.com/sheet/demo handles hundreds of columns. I guess you can always write custom component which will lazily render columns.
