Editing Tabular data
You can edit local Tabular data. Linked data cannot be edited.
Note that while the maximum file size recommendations for embedded media (File and Picture Attributes) hold for Tabular data, you should be aware that adding lots of files in Tabular data can quickly make datasheets impractical to load and/or edit. This is because editing Tabular data requires fetching all the rows (and their media data) from the database and saving back again.
