Column group rows appear only when you organize columns into groups. The
floating header row appears only when you set the floatingRowEnabled
property to true.
Set the column header height with the headerHeight property. Pass a
number value representing the height in pixels.
!demo:Column Header Height="./demos/column-header-height"
You can change the column header height after setup:
// Set the header height to 24px
grid.state.headerHeight.set(24);
When using column groups, some columns might not belong to any group or might belong to groups with fewer levels than the deepest group. In such cases, the column header spans multiple group rows, increasing its height based on the rows spanned.
!demo:Column Header Group Span="./demos/column-header-height-spans"
Use the headerGroupHeight property to set the height of each column
group header row. Column groups can form multi-level hierarchies.
!demo:Column Group Header Height="./demos/column-header-group-height"
You can change the column group header height by updating the
headerGroupHeight state:
// Set the column group header height to 30px
grid.state.headerGroupHeight.set(30);
The floating row appears as an extra header row under the column header.
It's useful for showing supplementary info or interactive components
like floating filters. Use the floatingRowHeight property to set its
height.
!demo:Floating Row Height="./demos/column-header-floating-row-height"
You can also update the floating row height dynamically:
// Set the floating row height to 24px
grid.state.floatingRowHeight.set(24);
