Sap.m.TableSelectDialog multiSelect behaviour in non multiSelect mode

Question

Hi All,
I am using sap.m.TableSelectDialog in my application and i can see that Ok button is only provided when multiSelect property is set to true. Moreover, in non mulltiSelect mode as soon as an item selection(item click) is made, dialog closes.
What i need is when i click an item it should get selected and Ok button should be there to confirm the selection thereby closing the dialog. Like i said this behaviour is available in multiSelect mode but the only thing i don't need is multi selection. User should be allowed to select only one item.
I have gone through TableSelectDialog,js and there seems no way to override the current behaviour in both the modes. Even i cannot see a possibility that extending the control will also help me. One possible way which i see is instead of using this control, i can use Bar, table, search and dialog independently but the only trade off is more view and controller code.
I simply don't want more code as UI5 already provides the exact control for my use case. Only problem is multi selection. Is it possible to achieve what i need, with this control?

Thanks for the reply, this actually explains it pretty well!
I set the defaultSpan to "L6 M6 S12", so got my two elements in my grid (list and table) which now each take up half of the screen on large and medium screens, and which get displayed one below the other on small/mobile screens.
Thats almost how I wanted it, but now the list takes up too much (-> wastes) space. I pretty much want the ratio to be 25% list, 75% table. I tried to set the width of the controls to these values, but now the list ist small and the table still starts at 50% width instead of where the list ends.
Is there a way to make the first control in the grid take up less space than the second one?

Felix
