Enhancing LWC Datatable Functionality with Pagination and Search Capabilities

Introduction

Lightning Web Components (LWC) stand out as custom HTML elements crafted with modern HTML and JavaScript. Utilizing core Web Components standards, LWC optimizes performance exclusively for browsers supported by Salesforce. Its lightweight nature, rooted in code native to browsers, ensures exceptional performance. Notably, the majority of the code is standard JavaScript and HTML.

Challenges with Out-of-the-Box (OOB) Datatable

The lighting-datatable component proficiently displays tabular data, allowing column customization based on data types. While it boasts several built-in features, handling datasets exceeding 100 rows necessitates the implementation of pagination or infinite scroll for an enhanced user experience.

This article addresses the creation of a versatile data table component, incorporating key features such as pagination, row selection, static headers, and global search. The source code for this component is available in the lwcDatatable repository.

Creating the Generic Component

Initiate the creation of the generic data table component named “lwcDatatableUtility.”

1. Develop a Lightning Web Component with the designated name, "lwcDatatableUtility."
2. Substitute the code in lwcDatatableUtility.js, lwcDatatableUtility.html, and lwcDatatableUtility.css with the corresponding content from lwcDatatableUtility.
3. Deploy the lwcDatatableUtility component to your Salesforce Org.
4. The generic data table component is now ready for integration into your own components.

How to Use

To utilize the lwcDatatableUtility component, follow these steps:

1. Declare the following variables in lwcDatatableUtility.js, which will be used to send data to lwcDatatableUtility for rendering the table:

let allRecords;
let columns;

1. In the .html page, include lwcDatatableUtility to render the table:

<c-lwc-datatable-utility records={allRecords} 
total-records={allRecords.length} 
columns = {columns}
key-field="Id"
show-search-box="true"            
max-row-selection={allRecords.length}
onpaginatorchange={handlePaginatorChange}
onsetselectedrecords={handleAllSelectedRows}>
</c-lwc-datatable-utility>

For an example of how to use lwcDataTableUtility, refer to the updateMultipleCases component.

These steps provide a streamlined approach to implementing and utilizing the generic data table component within your Salesforce environment.
