Your main tool would be
你的主要工具是
Console.WriteLine("{0,5} {1,10} {2,-10}", s1, s2, s3);
The ,5and ,10are width specifiers. Use a negative value to left-align.
的,5和,10是宽度说明。使用负值左对齐。
Formatting is also possible:
格式化也是可能的：
Console.WriteLine("y = {0,12:#,##0.00}", y);
Or a Date with a width of 24 and custom formatting:
或者一个宽度为 24 和自定义格式的日期：
String.Format("Now = {0,24:dd HH:mm:ss}", DateTime.Now);
Edit, for C#6
编辑，用于 C#6
With string interpolation you can now also write
使用字符串插值，您现在还可以编写
Console.WriteLine($"{s1,5} {s2,10} {s3,-10}");
Console.WriteLine($"y = {y,12:#,##0.00}");
String.Format($"Now = {DateTime.Now,24:dd HH:mm:ss}" );
You don't need to call String.Format()explicitly:
您不需要String.Format()显式调用：
string s = $"Now = {DateTime.Now,24:dd HH:mm:ss}" + " " + $"y = {y,12:#,##0.00}" ;

Use \t to put in tabs to separate the columns
使用 \t 放入制表符以分隔列

The easiest this you can do is to use an existing library
最简单的方法是使用现有的库
Install-Package ConsoleTables
And then you can define your table like so:
然后你可以像这样定义你的表：
ConsoleTable.From<Order>(orders).Write();
And it will give this output
它会给这个输出
| Id | Quantity | Name | Date |
|----------|----------|-------------------|---------------------|
| 3355 | 6 | Some Product 3355 | 18-04-2016 00:52:52 |
| 3355 | 6 | Some Product 3355 | 18-04-2016 00:52:52 |
| 3355 | 6 | Some Product 3355 | 18-04-2016 00:52:52 |
| 3355 | 6 | Some Product 3355 | 18-04-2016 00:52:52 |
| 3355 | 6 | Some Product 3355 | 18-04-2016 00:52:52 |
Or define a custom table
或者定义一个自定义表
var table = new ConsoleTable("one", "two", "three");
table.AddRow(1, 2, 3)
.AddRow("this line should be longer", "yes it is", "oh");
table.Write();
