这个之前也知道，不过今天看https://www.ag-grid.com/angular-data-grid/grid-interface/的时候见有提到，记录下：
Where the property is a boolean (true or false), then false (or left blank) is the default value. For this reason, on / off items are presented in a way that causes the most common behaviour to be used when the value is false. For example, suppressCellFocus is named as such because most people will want cell focus to be enabled.
