c: 绘制 table 的布局到控制台

Question

代码有效，但我不知道如何正确设置输出格式以匹配任何尺寸的布局（在本例中为虚线）的一致性？

#include <stdio.h>

int main(int argc, const char * argv[]) {

    int i=0, k = 0, total_x = 3, total_y = 4;
    char symbol = '+';




    for (k = 1; k <= total_y; k++) {

        // print symbol and row numbers
        if (k == 1) {
            printf("%3c | ",symbol);

            int temp;
            for (temp = 1; temp <=  total_x; temp++) {
                printf("%4d", temp);
            }
            printf("\n");

            for (temp = 1; temp <  total_x*5; temp++) {
                if (temp == 5) {
                    printf("+");
                }
                printf("-");
            }
            printf("\n");
        }

        printf("%3d | ",k);

        for (i = 1;  i <= total_x; i++) {
            printf("%4d", k + i);
        }
        printf("\n");
    }

       return 0;
}

当total_x = 3, total_y = 4时输出;:

  + |    1   2   3
----+----------
  1 |    2   3   4
  2 |    3   4   5
  3 |    4   5   6
  4 |    5   6   7

想要的结果：

  + |    1   2   3
----+--------------
  1 |    2   3   4
  2 |    3   4   5
  3 |    4   5   6
  4 |    5   6   7

当total_x = 10, total_y = 4时输出:

  + |    1   2   3   4   5   6   7   8   9  10
----+---------------------------------------------
  1 |    2   3   4   5   6   7   8   9  10  11
  2 |    3   4   5   6   7   8   9  10  11  12
  3 |    4   5   6   7   8   9  10  11  12  13
  4 |    5   6   7   8   9  10  11  12  13  14

想要的结果：

  + |    1   2   3   4   5   6   7   8   9  10
----+------------------------------------------
  1 |    2   3   4   5   6   7   8   9  10  11
  2 |    3   4   5   6   7   8   9  10  11  12
  3 |    4   5   6   7   8   9  10  11  12  13
  4 |    5   6   7   8   9  10  11  12  13  14

有没有可以帮助我正确打印的 printf 函数？非常感谢！

您可以像这样使破折号打印得更漂亮：

printf("----+--");
for (temp = 1; temp <= total_x; temp++) {
    printf("----");
}
printf("\n");

或更正您所做的算术：

for (temp = 1; temp <= total_x*4+6; temp++) {
    if (temp==5)
        printf("+");
    printf("-");
}
printf("\n");
