其实利用 el-table 组件中的 cell-style 属性处理这个功能非常简单它允许开发者通过提供对象或返回样式的函数来自定义每个单元格的样式通过这个特性我们就可以很轻松的实现这个功能。
el-table :dataproductList.tableOne :cell-stylegetCellStyle(参数1, 参数2,...)/el-table核心代码 getCellStyle(currentData, compareToData) {return ({ rowIndex, column }) {const { property } column;const currentValue currentData[rowIndex]?.[property];const compareToValue compareToData[rowIndex]?.[property];return currentValue ! compareToValue ? { color: red } : null;};
},首先在 getCellStyle 函数中会接受两个参数 currentData 和 compareToData。这个函数会返回一个回调函数用于设置表格单元格的样式回调函数接受一个参数 { rowIndex, column }其中 rowIndex 是当前行的索引column 是当前列的信息。函数内部通过 column 获取到属性名 property然后函数通过索引 rowIndex 和属性名 property 从 currentData 和 compareToData 中获取对应的值 currentValue 和 compareToValue最后函数判断 currentValue 和 compareToValue 是否相等如果不相等则返回一个样式对象 { color: red }表示将单元格的文字颜色设置为红色如果相等则返回 null表示不设置样式。 实现效果 完整功能代码
