Hi A Gunale,

I have understood your requirement of Create table with input fields using aura component and got a solution over it. I hope it will help you.

Component :-

<aura:component implements="force:appHostable,flexipage:availableForAllPageTypes"
                access="global"
                controller="AccountController">
    <aura:attribute name="data" type="Object"/>
    <aura:attribute name="columns" type="List"/>
    <aura:attribute name="recordId" type="String"/>
    <!-- This attribute will hold the update records from data table-->
    <aura:attribute name="updatedRecord" type="Object[]" />

    <aura:handler name="init" action="{!c.doInit}" value="{!this}"/>

    <!-- You must define keyField as 'Id' to save the record back in Salesforce
'onsave' attribute will executed when user clicks on save button -->
    <lightning:card title="Account Editable Datatable">
        <lightning:datatable
                             aura:id="accountDataTable"
                             columns="{! v.columns }"
                             data="{! v.data }"
                             keyField="Id"
                             onsave ="{!c.onSave}"
                             hideCheckboxColumn="true"
                             onrowaction="{! c.handleRowAction }" />
    </lightning:card>
</aura:component>

JS controller :-
({
    
    doInit : function(component, event, helper) {        
        component.set('v.columns', [
            {label: 'Name', fieldName: 'Name', editable:'true', type: 'text'},
            {label: 'Phone', fieldName: 'Phone', editable:'true', type: 'phone'},
            {label: 'Rating', fieldName: 'Rating', editable:'true', type: 'text'},
            {label: 'Custom Field', fieldName: 'My_Custom_Field__c', editable:'true', type: 'text'}
        ]);        
        helper.getAccounts(component, helper);
    },

    
    onSave : function (component, event, helper) {
        helper.saveDataTable(component, event, helper);
    }
})

JS helper :-
({
    getAccounts : function(component, event, helper) {
        var action = component.get("c.getAccounts");
        action.setCallback(this,function(response) {
            var state = response.getState();
            if (state === "SUCCESS") {
                component.set("v.data", response.getReturnValue());
            }
        });
        $A.enqueueAction(action);
    },

    saveDataTable : function(component, event, helper) {
        var editedRecords =  component.find("accountDataTable").get("v.draftValues");
        var totalRecordEdited = editedRecords.length;
        var action = component.get("c.updateAccounts");
        action.setParams({
            'editedAccountList' : editedRecords
        });
        action.setCallback(this,function(response) {
            var state = response.getState();
            if (state === "SUCCESS") {
                //if update is successful
                if(response.getReturnValue() === true){
                    helper.showToast({
                        "title": "Record Update",
                        "type": "success",
                        "message": totalRecordEdited+" Account Records Updated"
                    });
                    helper.reloadDataTable();
                } else{ //if update got failed
                    helper.showToast({
                        "title": "Error!!",
                        "type": "error",
                        "message": "Error in update"
                    });
                }
            }
        });
        $A.enqueueAction(action);
    },

    showToast : function(params){
        var toastEvent = $A.get("e.force:showToast");
        if(toastEvent){
            toastEvent.setParams(params);
            toastEvent.fire();
        } else{
            alert(params.message);
        }
    },

    
    reloadDataTable : function(){
    var refreshEvent = $A.get("e.force:refreshView");
        if(refreshEvent){
            refreshEvent.fire();
        }
    },
})

Apex Class :-

public class AccountController {
@AuraEnabled
    public static List<Account> getAccounts(){
        return [SELECT
               Id, Name, Phone, Rating, My_Custom_Field__c
               FROM Account LIMIT 200];
    }

    @AuraEnabled
    public static boolean updateAccounts(List<Account> editedAccountList){
        try{
            update editedAccountList;
            return true;
        } catch(Exception e){
            return false;
        }
    }
}

I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.
