Tree-table view

[AlexLvovsky]

I would like to have a tree-table view, that all the below logic will be inside.
Features:
expand/collapse rows
sort by level

Something like this

[andrewseguin]

You should be able to do this using the table currently, and to make it easier you can use the TreeControl to help you traverse your data and manage expansion state

@andrewseguin
This is great, but how can I sort this table by column?
MatTreeFlatDataSource doesn't support sort

[andrewseguin]

If you want more functionality, I recommend putting in the MatSort and listening for its events to sort the data that you provide to the data source. We do not have plans to add a tree data source that sorts each level by a particular column.
