数据透视表值显示方式 | 功能例子 | SpreadJS JavaScript 学习指南

SpreadJS数据透视表提供showDataAs方法来以不同方式快速展示数据。这里有14种不同的展示数据方法可以使用。值显示方式名枚举值值显示方式所需的参数无计算 normal showDataAs 总计的百分比 percentOfTotal showDataAs 列汇总的百分比 percentOfRow showDataAs 行汇总的百分比 percentOfCol showDataAs 百分比 percent showDataAs, baseFieldName, baseFieldItemType, baseFieldItem? 父行汇总的百分比 percentOfParentRow showDataAs 父列汇总的百分比 percentOfParentCol showDataAs 父级汇总的百分比 percentOfParent showDataAs, baseFieldName 差异 difference showDataAs, baseFieldName, baseFieldItemType, baseFieldItem? 差异百分比 percentDiff showDataAs, baseFieldName, baseFieldItemType, baseFieldItem? 按某一字段汇总 runTotal showDataAs, baseFieldName 按某一字段汇总的百分比 percentOfRunningTotal showDataAs, baseFieldName 升序排列 rankAscending showDataAs, baseFieldName 降序排列 rankDescending showDataAs, baseFieldName 指数 index showDataAs 示例:
