DP - Bottom Up - Tabulation Solution

In the below example, aren't you already initializing the array to 0? So isn't the next for-loop to populate with 0's repetitive? Is there a reason to keep this?

    dp = [[0 for x in range(capacity+1)] for y in range(n)]
    
    # # populate the capacity = 0 columns, with '0' capacity we have '0' profit
    for i in range(0, n):
      dp[i][0] = 0
