set row/column span programmatically

I'm trying to make a dynamic layout to display data from a database, for that i'm using a tablelayoutpanel and I got it to where it puts the data in the fields I want it go to but I can't figure out how I would go about giving some of the fields a row or column span since some of them need to go over multiple fields

this is the code I use to create one of the labels that would need a columnspan

tableLayoutPanel1.Controls.Add(new Label()
{ Text = stat, Dock = DockStyle.Fill, BackColor = Color.Green, AutoSize = true }
, 7, row);

I did search on SO for a solution and I did find some that would set the columnspan, but they just wouldn't work with the way i create the labels.

tableLayoutPanel1.SetRowSpan([control name],[rowspan] );
//[] is what is supposed to be placed there

since this is the code I found and because I created the labels in the code I can't give the control name. (It's very possible due to a mistake made by me)

Add methods are typically return void. If you want to operate with the item, then it make sense to either do it before calling Add() (construct complete object) or create an instance in the normal way

var item = new Label() { Text = stat, Dock = DockStyle.Fill, BackColor = Color.Green, AutoSize = true };
// do something with item here
tableLayoutPanel1.Controls.Add(item, 7, row);
// or do something with item here, e.g.:
tableLayoutPanel1.SetColumnSpan(item, 2);

Your original code will work if you can add an identifying Name property:

tableLayoutPanel1.Controls.Add(new Label()
    { Name = "L1", Text = stat, Dock = DockStyle.Fill, 
      BackColor = Color.Green, AutoSize = true }, 7, row);

Now you can use that Name: 

tableLayoutPanel1.SetRowSpan(tableLayoutPanel1.Controls["L1"], 2 );

To create the Name you could use the Controls.Count property: 

string name = "L" + tableLayoutPanel1.Controls.Count.ToString("00");

After some more searching i found a way to do it. instead of trying to do it like this: 

tableLayoutPanel1.Controls.Add(new Label() 
{ Text = naam, Dock = DockStyle.Fill, BackColor = Color.Green, AutoSize = true }
, 2, row);

im now creating the labels that need columnspan like this

var label = new Label();
label.Text = naam;
label.Dock = DockStyle.Fill;
label.BackColor = Color.Red;
label.AutoSize = true;
tableLayoutPanel1.Controls.Add(label);
tableLayoutPanel1.SetCellPosition(label, new TableLayoutPanelCellPosition(2, row));
tableLayoutPanel1.SetColumnSpan(label, 2);

Set the ColumnSpan property of the label.
