display string in two columns for a tooltip in C#

In order to this u have to do a bit of formatting

white spaces are not so helpful

in order to implement the text in two columns u need to work out how many tabs u need to add between two columns of each row. Because 1st cel of 1st row might be too short and same of 1nd row might b too long. So just adding one tab in between two columns of each row will end up some this kind of formatting

b1 book1
gudbooks bok2
Books braveBooks
dontumindit myStuff
haythatscooliloveit Really

the reason is that 1st column of each row differs in length
to over come this problem, u need to work out whats the maximum length of the text which is going to be added, and for each row u need to work out how many tabs to be addedd

private void Form1_Load(object sender, EventArgs e)
{
    //strings with different lengths
    string[] arr = { "b1", "book1", "gudbooks", "bok2", "Books", "braveBooks", "dontumindit", "myStuff", "haythatscool,iloveit", "Really" };
    int maxlen = 0;

    // calculating maximum length only for 1st cell items
    // that is items on all even places in array
    for (int i = 0; i < arr.Length; i++)
    {
        if (i % 2 == 0)
            if (maxlen < arr[i].Length)
                maxlen = arr[i].Length;
    }
    MessageBox.Show(maxlen.ToString());
    // Minimum No of Tabs which wil be added to maximum length cell
    int minimumTabSpace = 2;

    //getting Number of Tabs To overcome maxlength text
    int noOftabs = (maxlen / 8) + minimumTabSpace;
    string ToolTipText = "";

    for (int i = 0; i < arr.Length; i++)
    {
        ToolTipText += arr[i];
        if (i % 2 != 0)
        {
            //Insering New Line After every Two Cells
            ToolTipText += Environment.NewLine;
        }
        else
        {
            //Determining no. of Tabs for each Row
            //and inserting after 1st cell of each Row
            for (int j = 0; j < noOftabs - (arr[i].Length / 8); j++)
                ToolTipText += "\t";
        }
    }
    toolTip1.SetToolTip(button1, ToolTipText);
}

if u have too many white spaces in the text, then u need to work more to get proper allignment.

Best of Luck.
