title: Add/Update data in specific row of CSV file
body: <p>I developed a program - a data matcher of two CSV file. Sample input of the data in CSV file is below.</p>
  
  <p>user_transaction:</p>
  
  <p>user name       |        email       |      amount  |  blank   | total  |  n/a |  ok | bank name | date</p>

  <p>bank_transaction:</p>
  
  <p>date | transact details | n/a | location  | blank  | <strong>for status</strong> | amount </p>
  
  <p><a href="https://i.stack.imgur.com/IBuwL.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/IBuwL.jpg" alt="enter image description here"></a></p>
  
  <p>So what my program do is looking for all bank transaction(date and amount) match to users data.</p>
  
  <p>Here is my code doing it..

  <p>Any idea?
  When clicking <strong>done</strong> of a specific row should add data to the status row from the bank_transaction CSV file. 
  My purpose here is to mark <code>done</code> all that I have check/confirm bank transaction detail.</p>
