在大多数编程语言中，可以使用嵌套循环来遍历一个二维数组，并删除相应的列。下面是几种常见编程语言的示例代码：

1. Python:

def delete_column(arr, column):
    for row in arr:
        del row[column]
    return arr

# 示例用法
arr = [[1, 2, 3],
       [4, 5, 6],
       [7, 8, 9]]

column_to_delete = 1
result = delete_column(arr, column_to_delete)

print(result)  # 输出: [[1, 3], [4, 6], [7, 9]]

2. Java:

public class Main {
    public static void main(String[] args) {
        int[][] arr = {{1, 2, 3},
                       {4, 5, 6},
                       {7, 8, 9}};
        
        int columnToDelete = 1;
        int[][] result = deleteColumn(arr, columnToDelete);
        
        for (int[] row : result) {
            for (int num : row) {
                System.out.print(num + " ");
            }
            System.out.println();
        }
        // 输出:
        // 1 3
        // 4 6
        // 7 9
    }
    
    public static int[][] deleteColumn(int[][] arr, int column) {
        for (int[] row : arr) {
            int[] newRow = new int[row.length - 1];
            int index = 0;
            for (int i = 0; i < row.length; i++) {
                if (i != column) {
                    newRow[index] = row[i];
                    index++;
                }
            }
            row = newRow;
        }
        return arr;
    }
}

3. JavaScript:

function deleteColumn(arr, column) {
    for (let i = 0; i < arr.length; i++) {
        arr[i].splice(column, 1);
    }
    return arr;
}

// 示例用法
let arr = [[1, 2, 3],
           [4, 5, 6],
           [7, 8, 9]];

let columnToDelete = 1;
let result = deleteColumn(arr, columnToDelete);

console.log(result);  // 输出: [[1, 3], [4, 6], [7, 9]]

以上代码示例提供了基本的思路，具体实现方式可能因编程语言和实际需求而有所不同。
