Feature Table

Overview

The Feature Table displays attribute data from a selected map layer in an interactive table. You can spatially filter the table by drawing or selecting a geometry on the map — only features that intersect the geometry are shown. The table supports sorting, column visibility, and export.

Key Features

Spatial filtering: Draw or select a polygon, circle, or rectangle to filter the table to intersecting features
Buffer support: Expand a point or line geometry by a specified distance before filtering
Layer support: Works with Feature Layers and Map Image Layer sublayers
Measure toggle: Display live area measurements while drawing
Export CSV (all selected rows): Export every selected row to CSV — batched and cancellable, so a "Select all" of tens of thousands of features exports them all, not just the ~2,000 the ArcGIS API's own CSV export is capped at
Export: Download filtered results as SHP or KML via the layer context menu

Accessing the Tool

Click the Feature Table icon in the right panel toolbar

Feature Table Icon

The Feature Table toolbar appears at the top of the panel and provides geometry input and control buttons:

Button	Tooltip	Description
Select Shape	Select Shape	Click on the map to select an existing polygon feature as the filter boundary
Draw Polygon	Draw Polygon	Click vertices on the map to draw a custom polygon
Draw Circle	Draw Circle	Click and drag to draw a circular boundary
Draw Rectangle	Draw Rectangle	Click and drag to draw a rectangular boundary
Edit Shape	Edit Shape	Edit the vertices of the current drawn or selected shape
Measure toggle	Show area while drawing	Display a live area label (hectares or m²) while drawing
Filter Features	Filter Features	Apply the geometry filter and open the Feature Table dialog
Reset	Reset	Clear the current geometry and reset the tool
Fullscreen	Open fullscreen	Expand the Feature Table dialog to fullscreen

Buffer

The Buffer section appears below the toolbar after a geometry has been drawn or selected. Use it to expand a point, line, or polygon geometry by a fixed distance before filtering.

Points and lines must be buffered before they can be used as spatial filters against polygon layers.

Control	Description
Distance input	Enter the buffer distance (must be greater than 0)
Unit selector	Choose the unit: Meters, Kilometers, Feet, or Miles
Apply button	Applies a geodesic buffer to the current geometry on the map

Using the Feature Table

Step 1: Draw or Select a Geometry

Feature Table Panel with layer, draw, and filter controls

Use the toolbar buttons to define the spatial filter boundary:

Select an existing polygon from the map by clicking Select Shape then clicking a feature
Draw a custom boundary using the Draw Polygon, Circle, or Rectangle buttons

Step 2: (Optional) Apply a Buffer

If your geometry is a point or line, enter a buffer distance and unit, then click Apply to convert it to a polygon before filtering.

Step 3: Filter Features

Click Filter Features to open the Feature Table dialog. The table shows all features from the selected layer that intersect the drawn geometry.

Feature Table Dialog

Feature Table dialog with config sidebar and No Layer Selected state

The Feature Table opens in a draggable, resizable dialog. The heading shows the selected layer name and field count (e.g., "Feature Table — Properties Layer (15 fields)").

The dialog is non-modal — you can continue interacting with the map while the table is open.

Left sidebar accordion panels:

Layer — Select the source layer to display in the table
Filter — Configure an attribute filter (Basic or Advanced)
Actions — Data management actions for the table

Main area — the interactive attribute data table with sorting and selection.

Selecting Rows

A selection toolbar sits above the table, with a live selection count. It controls which rows the Export CSV button will export.

Select page, Select all, Clear, the selection count, and Export CSV in the selection toolbar

Control	Description
Select page	Select every row on the current page only
Select all	Select every matching row across all pages, respecting the active filter (e.g. all 795 features, not just the visible page)
Clear	Clear the current selection
N selected	A live badge showing how many rows are currently selected
Export CSV	Export all selected rows to a single CSV file — see Export CSV (all selected rows)

Data Management

Click the Three-Dots (⋮) menu icon in the table toolbar for data management options:

Layer Management Options

Option	Description
Refresh Data	Reload the table data from the layer
Clear selection	Deselect all selected rows
Zoom to Selection	Zoom the map to the selected features
Show Selection	Filter the table to show only selected rows
Export selection to CSV	The ArcGIS JS API's built-in CSV export — a single request capped at ~2,000 rows. For larger selections use the Export CSV button instead (see Export CSV (all selected rows))

Export CSV (all selected rows)

The Export CSV button (next to the selection count, brand-blue outline, CSV icon) exports every selected row to a single CSV file — not just the rows on the current page.

This is not the ArcGIS API's CSV export

The ArcGIS Maps SDK for JavaScript (JS API) FeatureTable has its own built-in "Export selection to CSV" (in the three-dots ⋮ menu). That one issues a single query capped by the service's record limit, so it exports at most ~2,000 rows — if your selection is larger, it silently keeps only the first ~2,000.

Horizon's Export CSV button works around that: it fetches the selected features in batches (each kept under the service limit) and assembles the CSV in your browser, so it downloads every selected row — however many that is.

What's in the CSV:

All exportable fields in the layer (geometry, blob, and raster columns are skipped), using each field's alias as the column header
Coded-value domains are translated to their labels — the CSV shows what the table shows (e.g. "Hardwood"), not the raw stored code
Date fields are written as ISO timestamps
A UTF-8 byte-order mark is added so Excel reads accented characters correctly
Values are safely quoted (RFC 4180) and protected against spreadsheet formula injection (a cell starting with =, +, -, or @ is neutralised so it can't run as a formula when opened in Excel/Sheets)

The file name is <LayerTitle>_selected_<count>.csv (the layer title is sanitised to safe characters).

Progress & cancel:

A progress bar with a live "Exporting X of Y (Z%)" count appears under the toolbar during the export
A Cancel button (red outline) appears next to Export CSV while it runs — click it to stop a large export immediately
The export also stops cleanly if you close the table dialog mid-export

When the button is enabled: only when there is an active selection (use Select page or Select all first). It is disabled while a selection is in progress or while an export is already running.

TIP

To export all rows, click Select all (which selects every feature across every page, respecting the active filter), then click Export CSV.

Other formats (Shapefile / KML)

For geometry-bearing exports, use the Filter Tool → Statistics & Export (or the Filter Editor's Statistics & Export tab).

Troubleshooting

Issue	Solution
Table not populating	Verify a layer is selected and the filter geometry is valid
Filter button disabled	Draw or select a geometry first
Buffer Apply button disabled	Ensure a geometry is present and distance is greater than 0
Points/lines not filtering	Buffer the geometry first — only polygon boundaries can filter area layers
Layer not in dropdown	Ensure the layer is visible on the map
Export CSV button disabled	Select rows first with Select page or Select all; the button is also disabled while an export is already running
CSV only has the first ~2,000 rows	You used the three-dots Export selection to CSV (the ArcGIS JS API export, capped at ~2,000). Use the Export CSV button next to the selection count to get all selected rows
