Cell grid can change color and down the line in the title ?

In VB6.0 Do you know the name of the control cell grid in the image above there are two lines in the header and the grid can color, see attached image. we can see in the figure, in the title (framed blue rectangle) is the 3rd day 9 was split into two lines and grid can be colored as: red, blue, ... the name of a grid control on the name?

It looks more like a spreadsheet, but you might be thinking of a MSFLEXGRID, which can kind of do that type of thing.

Have MSFlexGrid controls got support features such as Split or Freeze Panes of microsoft excel ? or controls that support this feature ?

Nope. Not a spreadsheet. Maybe two of them side-by-side, but you'd have to write that yourself.
