_renderLastColumnAsSubBuckets
A TLV with ColumnHierarchy can choose to display its last level of the hierarchy as "sub-buckets" of the existing bucket headers.
To enable this, providing the attribute renderLastColumnAsSubBuckets on ColumnHierarchy
<ColumnHierarchy renderLastColumnAsSubBuckets="true"> <Column> <Name>header</Name> </Column> <Column> <Name>item</Name> </Column></ColumnHierarchy>Without renderLastColumnAsSubBuckets="true", this TLV might look like this:
With renderLastColumnAsSubBuckets="true", the TLV might look like this:
Note how each day bucket above has been split into two "sub buckets": one for Item1 and one for Item2.
If the last Column in ColumnHierarchy is rendered as sub-buckets then the attributes of the last column will not be rendered in sub-buckets header.
