The crystal report does not have the concept of cells. Merging here is about the following effect.
If we use lines and boxes to create tables, although we can use the method to suppress repeated display, the lines in each row are still in progress and cannot achieve the "merge" effect.
In this case, we can perform this operation.
Step 1:
First, draw a large box around the field. Note that the top edge of the box is on the header and the header is on. The lower edge is in the detailed information section, closely following the lower edge.
Step 2: press Ctrl, click the field in the detail section, right-click a field, and select "format object" in the menu"
(Sorry, this figure is just blocked by the red letter)
On the displayed page, switch to the "border" tab. Set "TOP" line to "single line"
Step 3: Set "suppress display if repeated" for the specified field to achieve the merging effect.
Note: the source data must be sorted by this field.
