GridView - invisible column and checkbox column

I'm using the GridView.   I want to make a column invisible.  It is bound to a DataTable.  I have encountered a number of issue in trying to accomplish this.  

The ColumnName of the column in the DataTable is used as the column header text.  If I set this  to nothing, I get default text in the Column Header of "Column1".   Because I can't set the ColumnName of the column to nothing, this prevent the column form being invisible even if I set the invisible property to false and width to 0.   Bottom line, I can't get this column to totally disappear.  Is there a trick?  The invisible column is an a key value for the data in the row.  Is there a way to associate a key value with the row, without using a distinct column?  

Also, one of my columns is a check box.  I get the check box in theGridView by using a column in the DataTable with DataType = System.Type.GetType("System.Boolean").  However, the check box column is disabled.  How can I make it enabled?

Bellow url give some information
Hi! You may hide your column during databound event of your row. Something like this
    protected void GridView1_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
        //assuming you want to hide column 0
        //you can hide to the user but still you can access its value
        e.Row.Cells[0].Attributes.Add("style", "display:none");

Your question regarding disabled checkbox, this is enabled during Edit Mode of your gridview. 

Hope this helps.

On how to enable the check box column, "enabled during Edit Mode of your gridview".  Could you provide code example?  I'm new to .NET...

Also, would you have any info on this:  I have the GridView on a panel, so that I can scroll it.  All controls have that little tab at the upper left.  I want to align the tops of the GridView and the panel.  However, I cannot, visually, move the GridView to align with the top of the panel - that  little tab seems to prevent this.  How can I align the top of the  GridView with the top of the panel?   If you know the answer, I'm open another question, because you should get the credit for it.
