[SalesForce] Disable Checkbox in pageblocktable

I am looking to disable checkbox based on matching value in field of "rep type" which is in User object and a field of "Doctype" which is in Account object

for example:

Reptype is red and Doctype values are Red,Yellow, Red + yellow.

Now I am trying to disable chechbox where Reptype field value matching values in Doctype
In this case , checkbox disabled for red and Red + yellow.

I know we can use disabled attribute where we can different combination to disable. But I want to get dynamically by matching values in both fields.

Please let me know If anyone have any difficulty in understanding.
