Column wise tooltip for table

[shamilh2o]

Is your feature request related to a problem? Please describe

Need to give a description about the values in a particular column when hover on top of the column name.

Describe the solution you'd like

I would like to have a feature to show a tooltip for each column name instead of having a single tooltip for the entire table. Something like shown below,

Describe alternatives you've considered

Tried to use the tooltip which already has for the entire table to convey the message. But that is not efficient when it come to the application.

Hi, I'm trying to work on this issue as a first time contributor. To my understanding, we want to be able to add an argument 'tooltip' when creating a column such as:

  page['example'] = ui.form_card(box='1 1 3 3', items=[
      ui.table(
          name='table',
          columns=[
              ui.table_column(name='name', label='Name'),
              ui.table_column(name='value', label='Value', tooltip="tooltip for column name value"),
          ], 
          rows=[
              ui.table_row(name='row1', cells=['item0', 0]),
              ui.table_row(name='row2', cells=['item1', 1]),
              ui.table_row(name='row3', cells=['item2', 2]),
          ],
          tooltip="tooltip for entire table"
      )
  ])

which should create a table like this:

Initially, I tried to edit an additional tooltip property into the table_column in ui.py and the interface TableColumn in the table.tsx so that the user can specify an argument; then change how the header is rendered in table.tsx; however I discovered that types.py is generated and I cannot modify h2o_wave.types.TableColumn. How should I approach this issue? Thanks in advance

Hey @yy30537, super sorry for the late reply, but Github didn't send me the notification.

As you correctly pointed out, types.py etc. are generated. You can generate them (along with bunch of other stuff) by running make generate in the root project. See our contributing guide to learn more.
