how to generate probability matrix with close probability value.

I want to generate probability matrix with all value of particular row (for each row) should be close to each other. i.e.

       0.2451    0.2431    0.2602    0.2516
       0.2620    0.2412    0.2447    0.2521
       0.2376    0.2629    0.2518    0.2477
       0.2442    0.2650    0.2347    0.2561
