Local storage

When local storage is activated, the following parameters are stored:

• Columns width

• Column states (shown or not)

• Show/hide column names

• Show/hide summary

• Show/hide filter

• Current filter

Selection

Rows can be selected the following ways:

Click

On row click with a single click, toggle single row selection, reset previous selection.

Selection before clicking

Selection after clicking

Ctrl-click

On row click with a single click holding control key, toggle selected row, keeping other selection.

Shift-click

On row click with two click holding shift key, selects all rows between begging and end rows, keeping other selection.

Drag-and-drop

On row click holding and releasing, selects all rows between beginning and end rows.

Journal

Alarm journal tracks user interactions as well as free-form writing. It supports GitHub Flavoured Markdown text formatting.

User can enter the journal for only the current alarm as well as all selected alarms.

A shortcut can be used to add an alarm while typing using control + enter. Adding to all alarms can be done with control + shift + enter.

Toolbar

The alarm toolbar contains different actions:

Refresh

On the refresh icon click, you can refresh manually the table. The button next to it allows you to toggle the auto refresh option, making the table refresh automatically.

Journal

You can open the journal when one or more alarms are selected.

Menu actions

All the menu actions defined in your configuration can be accessed from the toolbar when the conditions are met. See menus for more information about menus.

Filters and Views

You can apply one of the filters defined in your configuration. Theses filters can be filtered by using the properties includeFilters and excludeFilters. includeFilters specifies the filters wanted for this widget and excludeFilters the ones to remove. If you set both, it will first remove all filters not present in the include list and then remove, from that list, the filters presents in the exclude list.

Following the same principles, you can filter the table with a view, from views defined in your configuration. You have the possibility to filter these views in the same way that the filters.

The column views options are (in view):

• formatter: specifies the date format (see https://day.js.org/docs/en/display/format). Used by TIMESTAMP render.

• formatterExport: specifies the date Excel format export. Used by TIMESTAMP render when exporting.

• disableTimezoneExport: disables user timezone usage when exporting to Excel format. The date will be displayed in UTC. Used by TIMESTAMP render when exporting.

• schemaId: specifies the schema ID to use (ie. root.collection.schema) to query. Used by COLLECTION render.

• format: specifies the property to display from schema ID. Used by COLLECTION render.

• depth: specifies the depth at which to get nodes from. Used by COLLECTION render.

• samePage: specifies whether to open URL in the same page or not (boolean value). Used by URL render.

Change table structure

Three options can change the structure of the table:

• Show/hide column: display the names of the columns at the top of the table, as well as an option to select/unselect all the rows.

• Show/hide filter: display filters options for each column, depending on the type of value.

• Show/hide summary: display a summary at the bottom of the table (ie: rows, count, sum of a column,…).

Search

You can search in the table by searching for a text (column with text value) or for a tag.

Export

The export button can export multiples rows into an excel file. Either export every row or export only the ones selected.

Show/Hide column

You can show or hide a particular column with the Show Column Chooser. These will also change depending on the view.

Clear filters

Remove all current filters and reset the default ones.

Widget communication

Alarm live/history table support following operation:

• updateFilter(id: string) with filter id in parameter updates the table filter

• updateView(id: string) with view id in parameter updates the table view

• appendSort(columnName: string, direction: AlarmViewSortDirection) with colum name and direction (asc or desc, emptied toggles it) in parameter appends to the current sorting

• applySort(columnName: string, direction: AlarmViewSortDirection) with colum name and direction (asc or desc, emptied toggles it) in parameter overrides the current sorting

• clearSort(columnName: string) with colum name in parameter clears the column sorting

• clearSorts() clears the table sorting

• appendFilter(columnName: string, value?: string, operation?: string) with column name, value (empty clears filter) and operation (see below) in parameters appends to the current filtering

• applyFilter(columnName: string, value?: string, operation?: string) with column name, value (empty clears filter) and operation (see below) in parameters overrides to the current filtering

• clearFilter(columnName: string) clears filter for given column name

• clearFilters() clears all filters

• applySearch(value?: string) applies table search (among all fields) with value parameters (empty clears it)

• clearSearch() clears table search

Built-in filter operations are:

• contains (default)

• notContains

• startsWith

• endsWith

• equal

• notEqual

• greaterThan

• greaterThanOrEqual

• lessThan

• lessThanOrEqual

• between

• dayEqual

Widget context

The widget context can be access from menus in order to fetch these different values from the alarm table. Alarms objects are dependant on view used.

• alarms * all: all rows (list) * clicked: clicked row (object) * selected: selected rows (list) * column: column with name and title (object) * value: value of the cell

• columnFilter: current filters on the table (list)

• columnOrder: list of all columns names in order

• hiddenColumnNames: list of hidden columns

• defaultFilter: current filter,

• defaultViewId: current view,

• language: current language used
