如何将我的数据表显示为矩阵？
如何让我的数据表获得以下格式：
England Germany Holland Spain Germany Russia Japan
England x
Germany x
Holland x
Spain x
Germany x
Russia x
Japan x
之前我确实得到了一些答案，但那是另一种方式。我实际上希望我的数据表可用于此。如果你可以帮我解决如何在正确的坐标上显示输入，那也很好。
最好的问候

Matrix.TableName = "Matrix";

好的，我的例子有点晚了，但我仍然花了一些时间来做这个，所以我发布:) 示例代码打印表并要求在再次打印表以显示结果后输入列号，行号和值。请记住它的示例如何打印矩阵并编辑其值。
class Program
{
static void Main(string[] args)
{
DataTable Matrix = new DataTable();
Matrix.TableName = "Matrix";
Matrix.Columns.Add(new DataColumn(MakeStringBeutiful("Name")));
Matrix.Columns.Add(new DataColumn(MakeStringBeutiful("1 England")));
Matrix.Columns.Add(new DataColumn(MakeStringBeutiful("2 Germany")));
Matrix.Columns.Add(new DataColumn(MakeStringBeutiful("3 France ")));
Matrix.Rows.Add("1 England", " x ", " ", " ");
Matrix.Rows.Add("2 Germany", " ", " x ", " ");
Matrix.Rows.Add("3 France ", " ", " ", " x ");
PrintMatrix(Matrix);
Console.WriteLine("Enter column number:");
string sx = Console.ReadLine();
int x = int.Parse(sx);
Console.WriteLine("Enter row number:");
string sy = Console.ReadLine();
int y = int.Parse(sy);
Console.WriteLine("Enter value:");
string v = Console.ReadLine();
SetValue(x, y, v, Matrix);
PrintMatrix(Matrix);
Console.ReadLine();
}
private static void SetValue(int x, int y, string value, DataTable table)
{
table.Rows[y - 1][x]=MakeStringBeutiful(value);
}
private static void PrintMatrix(DataTable m)
{
string s = "|";
foreach (DataColumn item in m.Columns)
{
s += item.ColumnName+"|";
}
Console.WriteLine(s);
Console.WriteLine("-----------------------------------------");
string j = "|";
foreach (DataRow item in m.Rows)
{
foreach (object ob in item.ItemArray)
{
j += ob.ToString()+"|";
}
Console.WriteLine(j);
j = "|";
}
Console.WriteLine("-----------------------------------------");
}
private static string MakeStringBeutiful(string str)
{
while (str.Length < 9)
str += " ";
return str;
}
}
