how to print the contents of a 2 dimensional array to a text box in a table like format?

I need to print the contents of my 2 dimensional array to a textbox called txtExecute in a table like format just like the one below: 

        Mon    Tue    Wed    Thu    Fri
Week 1  1      2      3      4      5
Week 2  6      7      8      9      10
Week 3  11     12     13     14     15
Week 4  16     17     18     19     20

I have got the format of the weeks and days right but I can't figure out how to get the arrays values exactly like that. Here is my code so far:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    int[,] productsArray = new int[4, 5];

    private void AddValuesToArray() 
    {
        txtExecute.Text = "Filling the array with user input..." + "\r\n\r\n";

        String value;
        int num;

        for (int week = 0; week < productsArray.GetLength(0); week++)
        {
            for (int day = 0; day < productsArray.GetLength(1); day++)
            {
                value = Microsoft.VisualBasic.Interaction.InputBox("Enter value for " + day + " of week " + week, "Enter Value");
                try
                {
                    while (!(int.TryParse(value, out num)))
                    {
                        MessageBox.Show("Not a valid number, try again.");
                        value = Microsoft.VisualBasic.Interaction.InputBox("Enter a number", "Enter Number");

                    }
                }
                catch (Exception)
                {
                    MessageBox.Show("Value entered is not in a valid format");
                }

                productsArray[week, day] += int.Parse(value);
            }               
        }
        txtExecute.Text += "The product allocation is as follows:" + "\r\n\r\n";
    }

    private void ArrayFormat()
    {
        txtExecute.Text += "\t" + "Mon" + "\t" + "Tue" + "\t" + "Wed" + "\t" + "Thu" + "\t" + "Fri" + "\r\n";
         for(int week = 0; week < productsArray.GetLength(0); week++)
         {
             txtExecute.Text += "Week " + week + "\t" +"\r\n";
             for (int day = 0; day < productsArray.GetLength(0); day++)
             {
                 txtExecute.Text += productsArray[0, 0];
             }
         }

    }

    private void btnExecute_Click(object sender, EventArgs e)
    {
        AddValuesToArray();
        ArrayFormat();
    }
 }

}

And here is the output I am getting:

        Mon    Tue    Wed    Thu    Fri
Week 0  
1111Week 1  
1111Week 2  
1111Week 3  
1111

I realise I am only outputting 1 element, and I will have to print out the rest but I want to solve this problem first.

So, your ArrayFormat() function should be like this ...

private void ArrayFormat()
{
    txtExecute.Text += "\t" + "Mon" + "\t" + "Tue" + "\t" + "Wed" + "\t" + "Thu" + "\t" + "Fri" + "\r\n";
     for(int week = 0; week < productsArray.GetLength(0); week++)
     {
         txtExecute.Text += "Week " + week + "\t";
         for (int day = 0; day < productsArray.GetLength(0); day++)
         {
             txtExecute.Text += productsArray[week, day] + "\t";
         }
         txtExecute.Text += "\r\n";
     }
}

EDIT:

txtExecute.Text += "\tMon\tTue\tWed\tThu\tFri\r\n";

is shorter

EDIT:

txtExecute.Text += "Week " + (week+1) + "\t";

to start from Week 1

You're always outputting the same array element.

for (int day = 0; day < productsArray.GetLength(0); day++)
{
     txtExecute.Text += productsArray[week, day];
}

This will solve that problem.

Replace your tabs with spaces and use String.PadRight in ArrayFormat method. And adding array members with productsArray[0, 0] doesn't help you, either. Replace it with productsArray[week, day];
