You are welcome!
At the first look TreeGrid is wrong choice for your requirements. Probably grid with subgrids is what you really need? You will display 10 accounts in the grid having pagination. I would recommend you to add searching toolbar to the grid. If you just add subGrid: true option to the account grid the column with “+” will be add and if the user click on the icon you can create any custom information below the expended row. Typically one creates subgrid with some kind of details inside of subGridRowExpanded.
I recomend you additionally to read the answer which could be helpful in your case.
