Dataframe
Table (also known as a dataframe) is a two-dimensional structure with named columns of different types. Supported types
are: string
, bool
, int
, bigint
, double
, qnum
, datetime
.
Dataframes are visualized using the grid viewer.
Column
Dataframes consist of columns. In addition to the data type, a column can be associated with tags that specify units, data format, semantic type, tooltip content and so forth.
To view column properties, right-click a column header and select Properties... The Context Panel updates to shows the column's properties.
Metadata
Like columns, each table can be annotated with attributes in the form of key-value pairs. Datagrok automatically annotates certain tables with metadata (such as the source of the table, or time of import, etc). To edit metadata manually, right-click a column header and select Column Properties....
You can search tables by metadata in projects.
