Description

Data Table widget receives one or more data sets on its input and presents them in a spreadsheet format. Data instances may be sorted by attribute values. Widget also supports manual selection of data instances.

Data table with Iris data set
  1. The name of the data set (e.g., inherited from the name of the input data file) with a table of data instances (in rows) and their attribute values (columns). In the example shown the data set is sorted by the attribute “sepal length”.
  2. Info on current data set size and the number and types of attributes.
  3. Meta attributes are not included in this example data set, the corresponding option is dimmed. Use “Restore Order” button to reorder data instance after attribute-based sorting.
  4. Values of continuous attributes can be visualized with bars.
  5. Data instances (rows) can be selected and sent to the widget’s output channel.
  6. Adds an entry with the entire data table to the current report.

Example

We used two File widgets, read the iris and glass data set (provided in Orange distribution), and send them to the Data Table widget.

Example data table schema

Selected data instances in the first Data Table are passed to the second Data Table. Notice that we can select which data set to view (iris or zoo); change from one data set to another alters the communicated selection of the data instances if “Commit on any change is selected”.
