vs2019 c#编译过程中制表符出现失灵,本来输出格式应该是三角乘法口诀,但\t未实现作用

using System;
using System.Reflection.Metadata;
using System.Reflection.Metadata.Ecma335;

namespace study
{
    class Program
    {
        static void Main(string[] args)
        {
            for (int i = 1; i <10; i ++)
            {
                for (int j = 1; j <= i; j++)
                {
                    Console.WriteLine("{0}*{1}={2}\t", i, j,i*j);
                }
            }
            Console.ReadKey();
        }
    }
}

WriteLine每次都换行，而是每个i后才换行

            for (int i = 1; i <= 9; i++)
            {
                for (int j = 1; j <= i; j++)
                {
                    Console.Write(j + "*" + i + "=" + i * j + "\t");
                }
                Console.WriteLine();
            }

由于console.writeline()是将当前行的终止符写入输出，自动换行；你要想实现可以换成
for (int j = 1; j <= i; j++)
{
Console.Write("{0}*{1}={2}\t", i, j,i*j);
}
Console.WriteLine();
