In relational databases, a database object is a structure that is used to either store or reference data. Data in a table is stored in a cell that is an intersection of a vertical column and horizontal row. The table has a specified number of columns, but can have any number of rows. With IntelliJ IDEA, you can perform data manipulation and data definition operations with tables.

Viewing modes for tables
When you double-click a table in the Database tool window ( ), the table opens in the data editor. You can browse and edit table data in three modes: Table, Transposed Table, and Tree. To switch between these modes, click the Show Options Menu button (), navigate to View as and select the mode that you need.
Table: the default viewing mode of table data. Data in a table is stored in a cell that is an intersection of a vertical column and horizontal row.
Transposed Table: viewing mode in which rows and columns are interchanged.
Tree: viewing mode in which data is displayed in the key-value table with the possibility to expand the key cell if it contains children nodes. Data from the expanded children node is distributed between key and value columns. You might consider using this mode to work with JSON and array data.
