title: Setting SharePoint List Permission by row (Based on name of user)
body: <p>Got a SharePoint List permissions question for you.</p>
  
  <p>What I have is a huge list. One of the columns in this list has a "Person/Group" that's responsible for that item. </p>
  
  <p>(The administrator creates the records (rows) and 'assigns' each row to a person, whose username goes into the "Person/Group" column)</p>
  
  <p>I want SharePoint to allow the person in that column to have access to only see and edit that particular row. In other words, unless the person has been assigned to a row by the site administrator, they won't be able to see the row or edit it.</p>
  
  <p>Example:</p>
  
  <pre><code>+-------+--------+--------+--------+--------------------+
  | Title | Data 1 | Data 2 | Data 3 | Person responsible |
  +-------+--------+--------+--------+--------------------+
  | A     |      1 |      2 |      3 | Steve              |
  | B     |      4 |      5 |      6 | Harry              |
  | C     |      7 |      8 |      9 | Sally              |
  | D     |     10 |     11 |     12 | Steve              |
  +-------+--------+--------+--------+--------------------+
  </code></pre>
  
  <p>So in this table, Steve can only see and edit Row A and D. Harry can see and edit only column B. Sally can see and edit only column C.</p>
  
  <p>What's the easiest way to achieve this, please? If it can be achieved at all.</p>
  
  <p>I apologise if this is trivial/duplicate question.</p>
  
  <p>P.s. I'm using SharePoint 2003 (I know.. I know.. Please don't hate me. It's not my decision.)</p>
  
  <p>Thanks v. much.</p>
