The panel's tab indicates the total number of features of the current layer between parenthesis.

data-table

The data panel is configured in this way:
- interactivity,
- filter,
- data settings.

Interactivity

When displaying numeric thematic data, bar charts are included in each row to help view and compare values in the data set. If a thematic analysis is currently displayed on the map, the colour used in the bar charts of the corresponding thematic data column are the same as the colours used in the legend.

When mousing over a row, the corresponding map feature is highlighted on the map.

You can click on a row to select it. The row will be highlighted in the data panel, the corresponding map feature will be highlighted on the map and that row will be added to the Selection panel. Note that you can perform multiple selections using the SHIFT or CTRL keys.

Double-click on a row to zoom to the feature on the map.

To sort rows in alphabetic or numeric order, click on the column title.

To reorder columns, click on the column title and drag to the new location.

To resize a column, click on the border of the column and drag to the desired width.

You can also Filter the rows on any data column to display only a subset of data.
