Topic: Join of cells Grid in FMX

All greetings!
Council is necessary.
There is Grid, in it a schedule of day.
In a DB each line is separate record.
It is necessary to make visually somehow similarity of join of cells in Excel.
I.e. it is necessary to occupy the schedule at 2 o'clock.
Thus the functional on events for a line of "the second hour" should be inaccessible.
Can erase at least boundary, i.e. leave value in the upper cells, and lower is simple not to display.
Or in the frame simply to outline both cells, thereby visually uniting.
How it is better for making?
