因为table的圆角实现比较复杂,所以写成一个less函数记录一下
使用
@import (reference) './utils.less';
table {
// 给不同的顶点设置统一的圆角
.add-radius-for-table(@border: 1px solid #000; @allRadius: 6px);
// 可以给不同的顶点设置不同的圆角
.add-radius-for-table(@border: 1px solid #000; @allRadius: 6px 7px 8px 9px);
}
工具函数 utils.less
/**
* @description: 设置表格table的圆角边框
* @param border: 表格的border样式:1px solid blue
* @param allRadius: 表格的radius:5px 或 5px 10px 或 5px 10px 20px等

.add-radius-for-table(@border, @allRadius) {
.getFullStrFromNum(@allRadius);
