At first glance, SeaTable looks like a spreadsheet, but in many places it works like a database. The tables in SeaTable do not stand isolated for themselves, but can be related to each other with the help of a link column rows .
More precisely, link columns create a link between entries. This works both with entries within a table and across multiple tables. In the end, SeaTable does not link entire tables with each other, but rows across table boundaries.
Since you implement this in SeaTable with columns, you will find all further explanations about links and link formulas in the Columns section.
