7e41f4b71Sopenharmony_ci> 该组件从API Version 7开始支持。后续版本如有新增内容,则采用上角标单独标记该内容的起始版本。
8e41f4b71Sopenharmony_ci## 子组件
9e41f4b71Sopenharmony_ci
10e41f4b71Sopenharmony_ci可以包含子组件。
11e41f4b71Sopenharmony_ci
12e41f4b71Sopenharmony_ciColumnSplit通过分割线限制子组件的高度。初始化时,分割线位置根据子组件的高度来计算。初始化后,后续动态修改子组件的高度则不生效,分割线位置保持不变,子组件高度可以通过拖动相邻分割线进行改变。
13e41f4b71Sopenharmony_ci
14e41f4b71Sopenharmony_ci初始化后,动态修改[margin](ts-universal-attributes-size.md#margin)、[border](ts-universal-attributes-border.md#border)、[padding](ts-universal-attributes-size.md#padding)通用属性导致子组件尺寸大于相邻分割线间距的异常情况下,不支持拖动分割线改变子组件的高度。
