I want to display adjacent rows of merged cell ranges without any grid lines between the rows but I have been unable to come up with a satisfactory solution. I suspect that this is something that is not supported but I thought I would check here before placing a feature request.
The situation I am trying to address is illustrated by dropping an advstringgrid on the form and then executing this code in the main form OnCreate handler:
The result is that there is a horizontal gridline separating the merged sections of the two rows. I understand the logic of why there is a line but it would be nice to be able to remove the gridline. Alternatively, it would be nice to be able to create non-rectangular merges.
One workaround I have tried is to set the merged cells to the gridline color but that is not very visually pleasing.
