Description

The plugin allows filtering the table data either by the built-in component or with the API.

See the filtering demo for examples.

Example

<HotTable
  data={getData()}
  colHeaders={true}
  rowHeaders={true}
  dropdownMenu={true}
  filters={true}
/>

Options

filters

Source code (opens new window)

filters.filters : boolean

The filters option configures the Filters plugin.

You can set the filters option to one of the following:

Setting	Description

Methods

addCondition

Source code (opens new window)

filters.addCondition(column, name, args, [operationId])

Adds condition to the conditions collection at specified column index.

Possible predefined conditions:

• begins_with - Begins with
• between - Between
• by_value - By value
• contains - Contains
• empty - Empty
• ends_with - Ends with
• eq - Equal
• gt - Greater than
• gte - Greater than or equal
• lt - Less than
• lte - Less than or equal
• none - None (no filter)
• not_between - Not between
• not_contains - Not contains
• not_empty - Not empty
• neq - Not equal.

Possible operations on collection of conditions:

• conjunction - Conjunction (opens new window) on conditions collection (by default), i.e. for such operation:
  c1 AND c2 AND c3 AND c4 ... AND cn === TRUE, where c1 ... cn are conditions.
• disjunction - Disjunction (opens new window) on conditions collection, i.e. for such operation:
  c1 OR c2 OR c3 OR c4 ... OR cn === TRUE, where c1, c2, c3, c4 ... cn are conditions.
• disjunctionWithExtraCondition - Disjunction on first n - 1* conditions from collection with an extra requirement computed from the last condition, i.e. for such operation:
  c1 OR c2 OR c3 OR c4 ... OR cn-1 AND cn === TRUE, where c1, c2, c3, c4 ... cn are conditions.

* when n is collection size; it's used i.e. for one operation introduced from UI (when choosing from filter's drop-down menu two conditions with OR operator between them, mixed with choosing values from the multiple choice select)

Note: Mind that you cannot mix different types of operations (for instance, if you use conjunction, use it consequently for a particular column).

Example

const hotRef = useRef(null);

...

<HotTable
  ref={hotRef}
  data={getData()}
  filters={true}
/>

// access to filters plugin instance
const hot = hotRef.current.hotInstance;
const filtersPlugin = hot.getPlugin('filters');

// add filter "Greater than" 95 to column at index 1
filtersPlugin.addCondition(1, 'gt', [95]);
filtersPlugin.filter();

// add filter "By value" to column at index 1
// in this case all value's that don't match will be filtered.
filtersPlugin.addCondition(1, 'by_value', [['ing', 'ed', 'as', 'on']]);
filtersPlugin.filter();

// add filter "Begins with" with value "de" AND "Not contains" with value "ing"
filtersPlugin.addCondition(1, 'begins_with', ['de'], 'conjunction');
filtersPlugin.addCondition(1, 'not_contains', ['ing'], 'conjunction');
filtersPlugin.filter();

// add filter "Begins with" with value "de" OR "Not contains" with value "ing"
filtersPlugin.addCondition(1, 'begins_with', ['de'], 'disjunction');
filtersPlugin.addCondition(1, 'not_contains', ['ing'], 'disjunction');
filtersPlugin.filter();

destroy

Source code (opens new window)

filters.destroy()

Destroys the plugin instance.

disablePlugin

filters.disablePlugin()

Disables the plugin functionality for this Handsontable instance.

enablePlugin

Source code (opens new window)

filters.enablePlugin()

Enables the plugin functionality for this Handsontable instance.

filter

Source code (opens new window)

filters.filter()

Filters data based on added filter conditions.

Emits: Hooks#event:beforeFilter, Hooks#event:afterFilter

getDataMapAtColumn
