pagelimit	(Default: 3)	number		Specifies how many page navigation links to add to pagination. The pagesize must be set.
draggable	(Default: false)	boolean		Specifies whether rows should be draggable or not. whenever a drag happens and order is updated then onupdate event is fired. Inside event handler you can get the updated data inside event.detail.result.
row-delete	(Default: false)	boolean		Specifies whether each row includes a delete option or not. NOTE: if once deleted it gets removed from the table altogether. Whenever we delete ondelete event is fired. Inside event handler you can get the deleted data inside event.detail.result.

## Example c-data-table Component ``` ``` ## Example data JSON ``` [{ "email": "jsolitas@motorsrus.com", "company": "Motors R Us", "age": "44", "balance": "$11,500", "address": "846 Livonia Avenue, Siglerville, Maryland, 5503", "isActive": true }, { "email": "robasanjo@treeline.org", "company": "TreeLine Group", "age": "32", "balance": "$9,678", "address": "902 Myrtle Avenue, Rockhill, Delaware, 3863", "isActive": true }, { "email": "n-daily@dailys.com", "company": "Daily Corp", "age": "57", "balance": "$22,888", "address": "408 Aster Court, Riceville, Indiana, 9646", "isActive": false }, { "email": "g-gomez@dailys.com", "company": "Daily Corp", "age": "44", "balance": "$6,983", "address": "856 Benson Avenue, Ballico, North Carolina, 4930", "isActive": true } ]; ``` ## Available columns Attributes

Attribute	Value	Type	Required	Description

Attribute	Value	Type	Required	Description
fields	list	array		Sets group header description for every visible row after grouping. Each object takes a field name that has its own group desciption, which by default is the sum of all selected field from all the records.

groupFieldName		string	yes	The reference key (field name) from the data JSON used to group the table.

## Example group-by JSON ``` { "groupFieldName": "company", "fields": [ { "name": "balance", "methodToCalculateSummary": "" } ] }; ``` ## Available Event Listeners onupdate Triggers when table data changes. ondelete Triggers when a table row is deleted. onrowclick Triggers when a row is clicked and includes the record on which the click happens. Is inside `event.detail.result`. ## Adding Custom Column UI To add a custom column specify each column inside data table: ```

``` As you can see how we create a data table is not changed at all, the only piece that is different is for each column you want to show, you have to write its relevant column inside data table element. THE ELEMENT THAT IS SUPPORTED INSIDE DATA TABLE IS EITHER DATATABLECELL OR EXTENDED LWC OF DATA TABLE CELL. Each column element should have two mandatory attributes: a) data-field-name : This is the same field name we specify inside columns array as mentioned before. b) class : You should add a dataTableCell class for it to be treated a column UI. INSIDE EXTENDED COMPONENT YOU WILL HAVE FOLLOWING DATA: a) cellData : This is that particular column cell data. For eg: if this column field name is "email". this variable will contain related data to that field name. You can read it by "cellData.value" b) rowData: This contains complete row data as it is of one single record and can be used to show more data as well. c) columnData: This contains metadata of what you pass inside columns json. NOTE: Even if we just want to customize one column we have to specify all the columns inside data table. If you dont want to customize any column then keep inside of data table empty. NOTE: For now custom column UI support is not supported in GROUP BY tables. Examples of a custom column UI component. You can use it as a reference. Please look at above data table example. ## customDataTableCell ``` ``` ``` import {track} from 'lwc'; import dataTableCell from "c/dataTableCell"; export default class DataTableCellExtended extends dataTableCell { @track hiddenText= false; toggleText(){ this.hiddenText = !this.hiddenText; } } ``` ``` .tableRowCell{ display: table-cell; padding: 0.25rem 0.5rem; white-space: nowrap; position: relative; } .tableRowCell:first { border: 0; } ```
