Selectiongrid formatting with guistyle.wordwrap

Im using a selection grid for a simple table that i need to display. the window theyre in is fixed size with a fixed horizontal internal window and a scrollable vertical one. When an entry is too long i need it to use a new line like, say, excel would. by default the end gets chopped off

The only option in guistyle that seemed to make sense was guistyle.wordwrap. however when i set this to true it has the desired effect by going to the next line when neccessary but it also creates a huge gap between each one

i cant even see another entry in the window to show how big the gap is! Any ideas how i can fix this? or is there something else that provides a grid like selectiongrid?

 void OnGUI () {
         windowRect = GUI.Window(0, windowRect, GuiFunc, "Record");
     }
     
     Rect insideWindow;
     
     void GuiFunc(int id) 
     {
         
         GUI.BeginGroup(insideWindow);
         
         scrollPosition = GUILayout.BeginScrollView(scrollPosition, new GUIStyle());
         GUILayout.SelectionGrid(0, gui, 2, listStyle);
         GUILayout.EndScrollView();
         
         if (GUILayout.Button("Close"))
         {
             mouse = false;
             guiOn = false;
         }    
         
         GUI.EndGroup();        
         GUI.DragWindow();
     }
 
 void Start () {
         windowRect = new Rect(Screen.width/2 - 170, Screen.height/2 - 150, 340, 300);
         insideWindow = new Rect(0, 0, 340, 1000);
         
         listStyle.normal.textColor = Color.white; 
         listStyle.padding.left =
         listStyle.padding.right =
         listStyle.padding.top =
         listStyle.padding.bottom = 4;
         listStyle.fixedWidth = 150;
         //listStyle.fixedHeight = 30;
         //listStyle.stretchHeight = true;
         listStyle.wordWrap = true;
         listStyle.clipping = TextClipping.Overflow;
         
         
     }
