看dxdbgrid的帮助
The Express Quantum Grid has a unique feature ?the ability to place columns onto several lines and divide them into logical categories (sections).
Bands allow you to:
?Divide columns into logical sections.
?Place columns onto several lines so that users can view a great number of columns without using the horizontal grid scrollbar.
?Columns may have different heights. For example, 12 pixels for a string field and 36 (12*3) pixels for a memo column. This permits screen space to be used in the most visually attractive manner possible, since you are able to design small string fields having the same heights as your memo fields.
Let's create an example with DBDEMOS alias table (BIOLIFE.DBF).
Bind the ExpressQuantumGrid with a dataset linked to table BIOLIFE.DBF and create columns.
1. Call the band component editor. Click the right mouse button on the ExpressQuantumGrid and select 'Bands ?
2. In the bands editor click the 'Add' button twice to add two new bands.
3. Now select the First band and press F11 to call Delphi Object Inspector and set up properties of the first band.
W must now change the caption and Alignment.
Change the caption for the other bands to 'Picture' and 'Description'.
4. Now assign the ShowBands property to True to display bands.
5. Assign the HeaderPanelRowCount property.
Now the header area is enlarged.
6. Set the egoBandHeaderWidth (OptionEx) option to False to disable changing of the band width on changing header width.
7. Customize a column by drag &
drop or by changing BandIndex (the index of the band to which this column belongs), RowIndex (the index of the header row onto which the column is placed) and ColIndex (the column order in the row) properties.
8. Assign RowSeparatorLineWidth to 2. Make the width of a line between records 2 pixels.
Here is the result during column and band customization:
