title: Change Read Only attribute from sharepoint 2010 List Column
body: <p>I have created a list using "<strong>Custom List in Data Sheet View</strong>". After that I created around 10 columns in that list. Problem is only for one column, it is showing as read only, rest all are working fine!! Hence I cannot insert a row in the list(Data sheet view).</p>
  
  <p><strong>How can I remove that read only attribute from the column?</strong></p>
  
  <p>One more related question is, how to make the list editable to only one group and read only to other groups?</p>
  
  <p>Thank you, for your valuable inputs!!</p>
