[Solved] Align Horizontal Groups in Editor GUI

Dear Community,

I have programmed my own ‘EditorWindow’. In it I draw a table of bools like so:

I would like the horizontal row of numbers (starting with the label ‘x | z’) to be aligned with the rows of toggles beneath it. Because the numbers represent the x-coordinates for the toggles.

This is my code:
Please ignore the curly braces and such. It is a condensed script with only the important method show.

public class RoomEditorWindow : EditorWindow {

private Room target;
private bool[,] bools;

//here everything is drawn
private void OnGUI()
    {
        DrawObjectField();

        if (target != null)
        {
            DrawHexTable();

            DrawSelectButtons();
            ...
        }
    }

private void DrawHexTable()
{
        EditorGUILayout.BeginHorizontal();
        EditorGUILayout.LabelField("x  |  z");
        for (int i = 0; i < bools.GetLength(0); i++)
        {
            GUILayout.Label(i.ToString());
        }
        EditorGUILayout.EndHorizontal();

        EditorGUILayout.BeginVertical();
        for (int ir = 0; ir < bools.GetLength(1); ir++)
        {
            EditorGUILayout.BeginHorizontal();
            EditorGUILayout.LabelField((target.rows - (ir + 1)).ToString());
            for (int ic = 0; ic < bools.GetLength(0); ic++)
            {
                bools[ic, ir] = EditorGUILayout.Toggle(bools[ic, ir]);
            }
            EditorGUILayout.EndHorizontal();
        }
        EditorGUILayout.EndVertical();
}

//methods for drawing all the buttons etc.
private void DrawObjectField() 
private void DrawSelectButtons()
...
}

Should I use EditorGUI, instead of EditorGUILayout? Or is there a way to manipulate the distance between members of a horizontal group? E.G. with GUIstyle? I haven’t really grasped the means to manipulate layout.

I’d be grateful for any help.

I figured it out. The GUILayout class offers a GUILayoutOption to modify maxWidth for example.
