Align custom sprite custom inspector to the left

I have an object field custom inspector that shows a preview of the object sprite. I can not figure out how to align the preview to the left. It does not have a label, just a blank string, but If I remove that it does not show the preview at all. Inspector code is below

![public override void OnInspectorGUI()
    {
        EditorGUI.BeginChangeCheck();

        GridComponent = (DCCGrid)target;

        serializedObject.Update();

        EditorStyles.foldout.fontStyle = FontStyle.Bold;
        ShowCellList = EditorGUILayout.Foldout(ShowCellList, "Cell List");
        EditorStyles.foldout.fontStyle = standardEditorFontStyle;

        if(ShowCellList)
        {
            EditorGUI.indentLevel = EditorGUI.indentLevel + 1;

            ScrollPosition = EditorGUILayout.BeginScrollView(ScrollPosition, GUILayout.Height(200));

            List<GameObject> cellObjectList = new List<GameObject>(GridComponent.CellObjectList);
            foreach (GameObject cellObject in cellObjectList)
            {
                Transform buttonTransform = cellObject.transform.FindChild("Button Image");
                Image buttonImage = buttonTransform.GetComponent<Image>();

                
                GridComponent.Editor_IsFoldoutOpen = EditorGUILayout.Foldout(GridComponent.Editor_IsFoldoutOpen, cellObject.name);

                if (GridComponent.Editor_IsFoldoutOpen)
                {
                    //EditorGUILayout.Space();

                    EditorGUILayout.BeginHorizontal();
                    buttonImage.sprite = (Sprite)EditorGUILayout.ObjectField("", buttonImage.sprite, typeof(Sprite), allowSceneObjects: false);
                    EditorGUILayout.EndHorizontal();

                    Button buttonScript = cellObject.GetComponent<Button>();
                    SerializedObject serializableButtonScript = new SerializedObject(buttonScript);

                    
                    EditorGUILayout.BeginHorizontal();
                    SerializedProperty onClickEvent = serializableButtonScript.FindProperty("m_OnClick");
                    EditorGUILayout.PropertyField(onClickEvent, true);
                    EditorGUILayout.EndHorizontal();
                }
               
            }
            EditorGUILayout.EndScrollView();
            EditorGUI.indentLevel = EditorGUI.indentLevel - 1;
        }

        serializedObject.ApplyModifiedProperties();

        EditorGUI.EndChangeCheck();
    }

        EditorGUI.EndChangeCheck();
    }][1]

@NoiseyAgent I know is three years later, but I found a way to achieve this and I wanted to share my code just in case someone needs it in the future.
How I managed to align the EditorGUILayout.ObjectField to the left, is by using the GUILayout.Width() options, as follows.

spriteVar = (Sprite)EditorGUILayout.ObjectField("Sprite", spriteVar, typeof(Sprite), false, GUILayout.Width(214));

Using a value of 214 seems to work for me, independently of what the size of the editor window or custom editor has. A value lower than 214 will just make the sprite preview box smaller. A value larger than 214 will move the sprite preview box farther from the label as the value grows.
