GroupColumnTemplate | API Reference | ArcGIS Maps SDK for JavaScript 4.31

A GroupColumnTemplate formats and defines the structure of a GroupColumn within a FeatureTable widget.

The GroupColumnTemplate is set directly on the table's template or its view model. The FeatureTable's tableTemplate contains a collection of field/group column templates.

Property Details

autoWidth Inherited Property autoWidth Boolean Inherited from ColumnTemplateBase Since: ArcGIS Maps SDK for JavaScript 4.30 ColumnTemplateBase since 4.24, autoWidth added at 4.30.

Indicates if the column width will automatically adjust to account for large content. The column ignores the current width property when autoWidth is true.

Default Value:false

columnTemplates Property columnTemplates Array<(FieldColumnTemplate|GroupColumnTemplate)>autocast

A collection of field column templates and/or group column templates that represent an ordered list of column templates.

Column templates are designed to allow the developer the ability to define the structure for columns within the FeatureTable widget.

Example

// Create a new table template
const tableTemplate = new TableTemplate({
  columnTemplates: [{ // Autocasts to new GroupColumnTemplate
    type: "group",
    label: "Inspector information",
    columnTemplates: [{
      // Autocasts to new FieldColumnTemplate
      type: "field",
      fieldName: "inspector",
      label: "name"
    },{
      type: "field",
      fieldName: "inspemail",
      label: "Email address"
    },{
      type: "field",
      fieldName: "insp_date",
      label: "Date of inspection"
    }]
  }]
});

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor

The name of the class. The declared class name is formatted as esri.folder.className.

description Inherited Property description String Inherited from ColumnTemplateBase Since: ArcGIS Maps SDK for JavaScript 4.31 ColumnTemplateBase since 4.24, description added at 4.31.

A string description of the column to give context to what it represents.

See also

fieldName Inherited Property fieldName String Inherited from ColumnTemplateBase

The unique field name as defined by the data source.

flexGrow Inherited Property flexGrow Number Inherited from ColumnTemplateBase Since: ArcGIS Maps SDK for JavaScript 4.30 ColumnTemplateBase since 4.24, flexGrow added at 4.30.

Controls the flex-grow property for the column. When set to 0, cell width is fixed.

Default Value:1

formatFunction Inherited Property formatFunction FormatFunction Inherited from ColumnTemplateBase Since: ArcGIS Maps SDK for JavaScript 4.30 ColumnTemplateBase since 4.24, formatFunction added at 4.30.

Custom function for rendering cell content that is called when the column is rendered in the table. The function should return the formatted content to display within a table's cell. This can be a string, number, an HTML element, or equivalent node type (e.g. a Calcite component). If the content is an HTML element, it is appended to the root element. If the content is a string or number, it is set as the innerHTML of the root element. This property is useful when you want to customize the cell content. For example, you can use this property to create a custom cell renderer that displays a progress bar in the cell. The progress bar can be used to show the progress of a task.

Example

// The following example demonstrates how to use the formatFunction property to create a custom cell renderer that displays a progress bar in the cell. The progress bar can be used to show the progress of a task.
columnTemplate.formatFunction = ({ column, feature, index, value })=> {
  const progress = document.createElement("progress");
  progress.max = 100;
  progress.value = value;
  return progress;
};

frozen Inherited Property frozen Booleanreadonly Inherited from ColumnTemplateBase

Indicates if the the column is frozen in place at the beginning of the table. Column must be first in the FeatureTable's column's, or next to other frozen columns.

Default Value:false

frozenToEnd Inherited Property frozenToEnd Booleanreadonly Inherited from ColumnTemplateBase Since: ArcGIS Maps SDK for JavaScript 4.30 ColumnTemplateBase since 4.24, frozenToEnd added at 4.30.

Indicates if the column is frozen in place at the end of the table. Column must be last in the FeatureTable's column's, or next to other columns with frozenToEnd set to true.

Default Value:false

icon Inherited Property icon String Inherited from ColumnTemplateBase Since: ArcGIS Maps SDK for JavaScript 4.30 ColumnTemplateBase since 4.24, icon added at 4.30.

The string value indicating the icon displayed in the header cell of the column.

Method Details

addHandles Inherited Method addHandles(handleOrHandles, groupKey) Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, addHandles added at 4.25.

Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.

// Destroy the object
this.destroy();

Parameters

handleOrHandles WatchHandle|WatchHandle []

Handles marked for removal once the object is destroyed.

See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

Parameter

json Object
