Hi,
Sorry for the inconvenience. The table component went through some major architectural refactoring to make way for the Alarm Status Table and quite a few feature requests. During this refactor, the freezing of table column and rows was classified as a low priority item to be reintroduced at a later date. You are the first since to bring it up. The task is currently sitting in our backlog to be worked on this week. I will update you as soon as it is reintroduced. Thanks!
