How to add a new column to editable lightning table

Hi All,

I am working on a requirement where i am supposed to make the table editable and capture values. The challenge here is that i have to capture values from this table and store it in another object so i think i am supposed to add a new column to lightning datatable using wrapper.

The user should enter values in columns amount and reason which i am planning to implement through wrapper but how to set values is something which is confusing me and i am not sure if this approach will work. Please check my code and let me know if you have any suggestions.
Component Code:

<aura:component controller="OpportunityAdjustmentController">
    <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>
    <aura:attribute name="OppId" type="Id" />
    <aura:attribute name="listOfAdjustments" type="OpportunityLineItem[]" />
	<aura:attribute name="wrapperList" type="object"/>
    
  <div class="slds-p-around--large">
      
     
      <p style="color:red">{!v.wrapperList}</p>
      
  <!--https://www.lightningdesignsystem.com/components/data-tables/-->
    <table class="slds-table slds-table--bordered slds-table--cell-buffer">
