Element ui多选框实现单选且隐藏全选按钮

 添加表格多选框列

<el-table-column type="selection" width="55"></el-table-column>

通过 @selection-change="handleSelectionChange"实现单选逻辑

handleSelectionChange(e) {
            this.selectedItem = e
            if(e.length > 1) {
                this.$refs.multipleTable.clearSelection()
                this.$refs.multipleTable.toggleRowSelection(e.pop())
            }
        }

隐藏全选按钮

::v-deep thead .el-table-column--selection .cell{
    display: none;
}

实现效果:

 选中的值永远只有一项
