Export datagridview to word document c#

I'm trying to export data grid to word document. But instead of this result:

EmployeeID EmployeeName Birth Phone Address DateOfHiring Salary EmloyeeType
1           name          1     11    test    1.1.1111     1        testTy
2           name2         2     22    test    2.2.2222     2        test2Ty

I'm getting something like this:

 EmployeeID EmpoyeeName Birth   Phone   Address DateOfHiring    Salary
           EmployeeType
     1     name                                 1.1.1111

     2     name2                                2.2.2222

All record are mixed. How to save datagrid in the format that it originally was? Here is the code that I use to perform export:

private void ReportButton_Click(object sender, EventArgs e)
    {
        string filename = @"D:\...\AllEmployees.doc";
        ToCsV(dataGridView1, filename);
    }
private void ToCsV(DataGridView dGV, string filename)
    {
        string stOutput = "";
        // Export titles:
        string sHeaders = "";

        for (int j = 0; j < dGV.Columns.Count; j++)
            sHeaders = sHeaders.ToString() + Convert.ToString(dGV.Columns[j].HeaderText) + "\t";
        stOutput += sHeaders + "\r\n";
        // Export data.
        for (int i = 0; i < dGV.RowCount - 1; i++)
        {
            string stLine = "";
            for (int j = 0; j < dGV.Rows[i].Cells.Count; j++)
                stLine = stLine.ToString() + Convert.ToString(dGV.Rows[i].Cells[j].Value) + "\t";
            stOutput += stLine + "\r\n";
        }
        Encoding utf8 = Encoding.UTF8;
        byte[] output = utf8.GetBytes(stOutput);
        FileStream fs = new FileStream(filename, FileMode.Create);
        BinaryWriter bw = new BinaryWriter(fs);
        bw.Write(output, 0, output.Length); //write the encoded file
        bw.Flush();
        bw.Close();
        fs.Close();


    }
