</template><script>
export default {props: {titleMapList: {type: Array,},msgMapList: {type: Array,},type: {type: String,},},data() {return {mainSource: "",};},mounted() {this.titleMapList.forEach((item) => {if (item.isMain === "1") {this.mainSource = item.code;return;}});},methods: {getColumnStyle(column, row) {console.log("this.type------", this.type);if (this.type === "2") {// 变色 居右if (column.colorFlag === "1" &&row[column.code] != row[this.mainSource]) {return "color-class table-left";}// 不变色 居右if (column.isMain === "1" || column.colorFlag === "1") {return "table-left";}} else {if (column.colorFlag === "1") {if (row[column.code] != row[this.mainSource]) {return "color-class"; //'color-class'}}}},},
};
</script>

• 注意：表头插槽拿到的column 和内容插槽拿到的内容不一致，header插槽的label对应el-table-column的label，prop对应header插槽的property

效果：
