enginenocopy = engineno.replace(/^(.{4})(?:\w+)(.{4})$/, "\$1****\$2");

<el-table-column

                  label="身份证号码"
                  align="center"
                >
                  <template slot-scope="scope">
                  <p v-if="scope.row.credentialsNum != null && scope.row.credentialsNum != '' "> {{scope.row.credentialsNum.replace(/^(.{6})(?:\d+)(.{4})$/, "$1****$2")}} </p>
                  <p v-else>未知</p>
                  </template>
