I have created a lightning component that iterates over column data and row data and in between this iteration i am calling my other lightning component that basically generates data for the table. The code looks like this:

<table class="slds-table slds-table--bordered slds-table--cell-buffer slds-box" style="height;300px">
    <thead>
        <tr class="slds-text-heading--label">
            <aura:iteration items="{!v.columns}" var="ct">
                <th scope="col" class="slds-is-sortable">
                    <div class="slds-truncate" title="{!ct.label}" onclick="{!c.sortAction}">{!ct.label}</div>
                </th>
            </aura:iteration>
        </tr>
    </thead>
    <tbody>
        <aura:iteration items="{!v.data}" var="acc">
            <tr>
                <aura:iteration items="{!v.columns}" var="col">
                    <td><c:DataGrigCell data="{!acc}" column="{!col}" relatedAssociations="{!v.relatedAssociations}" relatedContacts="{!v.relatedContacts}"/></td>  
                </aura:iteration>
            </tr>
        </aura:iteration>
    </tbody>
</table>

Now i want to know how can i implement client side sorting in this table in lightning component. Any kind of help is appreciated. Thanks in advance :)

  • We have a very good example here and the same will apply on your sortAction call. The example is for data table but the same dynamics will apply to your component. – manjit5190 May 10 at 12:50

You should try Lightning:DataTable with standard table features. You can use this generic component as well.

  • Hi Dheeraj, Thanks for this but for my requirement and type of data that i need to show in table cannot be achieved by lightning data table hence i have used custom table here. My each cell is a seperate lightning component because i had to show complex data something that we cannot achieve via lightning data table. – Rakshit Segwal May 10 at 14:37
  • @RakshitSegwal You can use a LWC data table, it allows you to extend it and define additional cell types with custom designs. This may be what you're looking for. – sfdcfox May 10 at 15:37
  • In lightning data table you can also define data type for each column and also do forming for each column. You can add custom action as well. There are lots of future available with solution in detail you can explore this link developer.salesforce.com/docs/component-library/bundle/… – Dheeraj Pandey May 11 at 7:00
  • You can use the sorting method used in CmAp_LightningDataTableController.Js method name is handleSort you can call this method from any button and use for sorting. Here sortedBy variable use column name, shortdirection define sorting order and Data variable is used for List of data displayed in table – Dheeraj Pandey May 11 at 7:03
