Merge in PG/plugin-report-doc-demo from release/10.0 to persist/10.0 * commit 'd51e4171edd2c1b536ad0149e34a2e41401eb6ab': 无JIRA任务 本地编译发现这个文档插件里面的类编译不通过了，纠正下，这个类在文档里没有用到，无需测试 REPORT-50982 保存模板至数据库后，读取带参数面板的报表会报错空指针，不带参数面板报表可以读取成功 REPORT-50963 优化程序数据集上层设计(abstracttabledata) rt REPORT-50963 新demo里面获取连接的逻辑跟老demo一致 补一下简单程序数据集demo REPORT-50963 优化程序数据集上层设计(abstracttabledata)，提交新demopersist/10.0
