Mobile two fingers tap event

[Heaven]

Hi, paramquery team:

1)
In my case, I want to apply the effect of "Frozen columns"(both top and left) on a table contain 25 columns, 1000 rows.
But when using two fingers to touch on the screen on simultaneously, the scrolling function of the grid would be disable ,
the same situation happens in the "Frozen columns" sample as well (Demo > Columns > Frozen columns).

2)
How could I speed it up when loading the table? ( and make it swipe more smoothly on mobile device )

the enviroment:
ParamQuery Pro v3.3.0
jQuery UI Touch Punch PQ_0.2.3
1.9.1/jquery.min.js
1.11.4/jquery-ui.min.js
1.11.4/jquery-ui.css

By the way, the data type is JSON, and it is just a static html file.

1) Thanks for reporting the issue caused by two finger tap. It's fixed now. You can recheck the demos.

2) Table loading can be speeded up by using virtual mode. ( virtualX: true, virtualY: true )

Swipe doesn't work in virtual mode, but scroll bars can be dragged with touch to scroll the grids.
