c - 如何将 printf 语句格式化为列名

Question

并非所有输出都与“column3”对齐。有没有一种特殊的方法可以减去某些数字不对齐的空格？我是否需要创建单独的 printf 语句？

下面是我的(看起来很可怕的)printf 语句

 printf("%d \t%lf \t\t%lf \t%lf    %lf \n", i, row1[i], row2[i], row3[i], row4[i]);

这是我得到的:

#   Column          Column1     Column2       Column3 
1   1.400000        32.300000   333.000000    66.500000 
2   11.200000       32.300000   11111.000000    35.900000
3   11.800000       32.300000   23333.000000    2.500000
4   1.500000        2.300000    32.000000    22.500000
5   1.000000        1.000000    333.000000    6.500000
6   11.000000       1.000000    3433.000000    665.500000

如何打印:

#   Column          Column1     Column2       Column3 
1   1.400000        32.300000   333.000000    66.500000 
2   11.200000       32.300000   11111.000000  35.900000
3   11.800000       32.300000   23333.000000  2.500000
4   1.500000        2.300000    32.000000     22.500000
5   1.000000        1.000000    333.000000    6.500000
6   11.000000       1.000000    3433.000000   665.500000

Answer 1

就像这样

printf("%15d\t%15lf\t%15lf\t%15lf\t%15lf\n",
    i, row1[i], row2[i], row3[i], row4[i]);
