v-if标签跟逻辑表达式为什么无效？

Question

这种情况下，按理来说，初始化会显示这个按钮啊，为什么操作栏下面不显示按钮？

<el-table-column label="操作">
          <template slot-scope="scope">
            <el-button v-if="outExamBoolean===true" @click="toExaming(scope.row.examId)" type="success">开始考试</el-button>
          </template>
        </el-table-column>
 
 
export default {
 
  name: "index",
  data() {
    return {
      //考试科目
      tableData: {
        examId:"",
        examName:"",
        examScore:"",
        examTime:"",
        createTime:"",
        deadlineTime:""
      },
      //Boolean
      outExamBoolean:true,
      examId:""
    }
  }
}
