Updated your code: I put the inline edit support as a child of the form and not the column. You can turn off inline edit support for columns in columns where you don't want it on. You don't want to put it as a child of the column as it tries to declare it with every iteration - that is not good. you can also use a formula to turn on or off inline edit support for different rows with different values. just set the rendered for the

<apex:inlineEditSupport disabled="false" rendered="{!formula here}" />

OR

<apex:inlineEditSupport disabled="{!formula here}" /> 

• needs to evaluate to false to be able to edit inline here - can wrap a TRUE formula in NOT() operator for that -->

that should work for you.
