I would agree with Robert. It is difficult to implement and will be used less often than sticky table headers, for example. Sticky columns are useful for wide tables, which are less common than tall tables. Taking into account that sticky columns could be easily workaround by assigning position:sticky to every corresponding table cell, I would suggest to disallow position:sticky for table columns. Slava
