Dynamic lightning table components help you to display the records in the table format easily. In this blog, we will understand how to get a row index of lightning table rows.
- If we want to do operation on the click on any column of table, we need a row index of respective rows.Firstly, we need to assign rowindex to rows as shown in the below code.
- In below table, we have assigned an “InputNumberLabel” class for lightning table data so that we can assign style for respective row.
- Also,we have included “label” attribute of <ui:inputNumber> for storing a row index.
<table data-reactroot="" class="slds-table slds-table--bordered">
<thead>
<tr class="">
<th scope="col">
<div class="slds-truncate">Product</div>
</th>
<th scope="col">
<div class="slds-truncate">Quantity</div>
</th>
</tr>
</thead>
<tbody>
<aura:iteration indexVar="rowIndex" items="{!v.GetProductData}" var="product">
<tr class="">
<td class="slds-text-align_right slds-text-body_small InputNumberLabel" data-row-index="{!rowIndex}">
<ui:inputNumber aura:id="idProduct" label="{!rowIndex}" value="{!product.Name}" change="{!c.DoAction}"/>
</td>
<td class="slds-text-align_right slds-text-body_small InputNumberLabel" data-row-index="{!rowIndex}">
<ui:inputNumber aura:id="idQuantity" label="{!rowIndex}" value="{!product.Quantity }" />
</td>
</tr>
</aura:iteration>
</tbody>
</table>- Get the row index of the respective row using following way:
DoAction: function(cmp,event,helper)
{
var rowIndex=event.getSource().get("v.label");
}
- Apply following css to the table data.
- visibility:collapse hides an element entirely (so that it doesn’t occupy any space in the layout), but only when the element is a table element.
- If we don’t apply visibility:collapse property, then rowindex will be display on the lightning Table UI.
.THIS .InputNumberLabel
{
visibility: collapse !important;
}
