Greetings to you!
Please try the below code, it is working fine. Kindly modify the code as per your requirement.
Visualforce:
<apex:page standardController="Account" extensions="AddDeleteRowWithNumberC" sidebar="false"> <apex:form > <apex:pageBlock title="Accounts" id="pb"> <apex:pageMessages /> <apex:variable var="rowNumber" value="{!0}"/> <apex:pageblockSection columns="1"> <apex:pageBlockTable title="Contacts" var="acc" value="{!attendeeList}"> <apex:column headerValue="No." style="width:20px; text-align:center;" headerClass="centertext"> <apex:outputText value="{0}" style="text-align:center;"> <apex:param value="{!rowNumber+1}" /> </apex:outputText> </apex:column> <apex:column headerValue="First Name" > <apex:inputField value="{!acc.FirstName}"/> </apex:column> <apex:column headerValue="Last Name" > <apex:inputField value="{!acc.LastName}"/> </apex:column> <apex:column headerValue="Phone" > <apex:inputField value="{!acc.Phone}"/> </apex:column> <apex:column headerValue="Email" > <apex:inputField value="{!acc.Email}"/> </apex:column> <apex:column headerValue="Action" > <apex:commandButton value="Delete Row" action="{!deleteRow}" reRender="pb"> <apex:param name="rowIndex" value="{!rowNumber}"/> </apex:commandButton> <apex:variable var="rowNumber" value="{!rowNumber+1}"/> </apex:column> </apex:pageBlockTable> <apex:commandButton action="{!addRow}" value="Add Account" reRender="pb"/> </apex:pageblockSection> <apex:pageBlockButtons > <apex:commandButton value="Save" action="{!ave}" /> <apex:commandButton value="Cancel" action="{!cancel}"/> </apex:pageBlockButtons> </apex:pageBlock> </apex:form> </apex:page>Controller:
