Ext js lock grid reconfig demo

Ext js lock grid reconfig demo

When the grid calls the reconfigure function, sometimes the lock Column cannot be correctly displayed. Add the attribute enableLocking: true to the Extjs 4.2.2.1144 grid to display it normally.

In addition:

ColumnLines: false, // whether to display the column border

RowLines: false, // whether to display the row border
