If Cells[r,c].ColSpan>1, this cell spans over (ColSpan-1) cells to the right:
Cell[r,c], Cell[r,c+1], ..., Cell[r,c+Cell[r,c].ColSpan-1].
In this case, all overlapped cells (Cell[r,c+1], ..., Cell[r,c+Cell[r,c].ColSpan-1]) are destroyed and equal to nil.
Number of cells in the row is still equal to the number of cells in all other rows, even with merging.
The same is with RowSpan: cell with RowSpan>1 spans over (RowSpan-1) cells below.
ColSpan and RowSpan example
Example: iterating through all cells of table:
for r := 0 to table.Rows.Count-1 do
for c := 0 to table.Rows[r].Count-1 do
if table.Cells[r,c]<>nil then
// ( Cells[r,c]=nil if it is overlapped by the top left cell)
You can get the top left cell which overlaps given cell with table.Rows.GetMainCell method:
function GetMainCell(ARow,ACol: Integer;
var MRow, MCol: Integer): TRVTableCellData;
