Vertical mode
The previous panel appeared in vertical mode because the default for
$cfg['DefaultPropDisplay']
is
3
. This means that for three columns or less,
the vertical mode is used, and for more than three, horizontal mode would be
automatically selected. Here, we can use a number of our choosing.
If we set
$cfg['DefaultPropDisplay']
to
'vertical'
, the panel to add new
columns (along with the panel to edit a column's structure) will be always presented
in vertical order. This parameter can also take a value of
'horizontal'
to force a
horizontal mode.
Editing column attribute
On the
Structure
page, we can make further changes to our table:
This panel does not allow every possible change to columns. It specifically allows:
• Changing one column structure, using the
Change
link on a specific column
• Removing a column, using
Drop
operation
• Adding a column to an existing
Primary
key
