开发中有一个需要呈现不同时间点各个气象要素的值需求我觉得一个table可以实现这类数据的展示只是因为时间点时关注的重点所以需要列选中效果清晰的展示时间点下的要素数据。我选择的是antd的table组件这个组件没有列选中的效果所以还是需要自己动手丰衣足食改造一下。
分析
这个功能的难点在于列选中效果我们需要给他一个背景加上边框虽然antd的table没有列选中效果但是它提供了customCellcustomHeaderCell我们可以根据这些回调函数的特点灵活使用实现列选中效果。
参数说明类型用途customCell设置单元格属性Function(record, rowIndex)根据activeColIndex参数为选中列包含的单元格添加class并且为最后一个单元格加上“lastCol”的class因为最后一个需要加上下边框customHeaderCell设置头部单元格属性Function(column)主要为选中列的第一个单元格加上class因为表头单元格需要加上上边框
