自定制浮动对象元素 | 功能例子 | SpreadJS JavaScript 学习指南

位置和大小可以通过两种方式来定制。比如：如果你在调整行高或者列宽的时候, 不想要浮动对象元素的位置以及大小跟着调整，你可以使用 dynamicMove 和 dynamicSize 方法来设置，例如：如果浮动对象元素的 dynamicMove 设置是 false 并且 dynamicSize 设置是 true，则不会有任何影响。如果你不想要用户通过用户界面来改变浮动对象元素，你可以使用 isLocked 方法来锁定它。不过在锁定浮动对象元素之前，你需要锁定表单。当浮动对象元素互相叠加的时候，你可以通过 zIndex 来设置浮动对象元素的层叠顺序。
