graph_objects.Table element takes up too much vertical space

[frobnitzem]

Plotly is an amazing tool! However, the plotly.graph_objects.Table element takes up way too much vertical space.

This can be observed even inside the tables rendered in the plotly documentation:
https://plotly.com/python/table/

On my firefox browser, the very first table in that page only needs about 150 px of vertical space, but is somehow requesting a height of 525!

The rendered HTML in question looks like:

<g class="table" overflow="visible"
   style="box-sizing: content-box; position: absolute; left: 0px; overflow: visible; shape-rendering: crispedges; pointer-events: all;"
   width="734" height="525" transform="">
<g class="table-control-view"...></g></g>

The other tables on that page have similar issues.

For a work-around, I noticed the dash-sample-apps manually create HTML table elements (e.g. make_dash_table in https://github.com/plotly/dash-sample-apps/blob/main/apps/dash-drug-discovery/helpers.py)

You can set accordingly the layout height and margin to remove the empty vertical space.

import plotly.graph_objects as go

fig = go.Figure(go.Table(header=dict(values=['A Scores', 'B Scores']),
                         cells=dict(values=[[100, 90, 80, 90], [95, 85, 75, 95]])))
fig.update_layout(height=100, margin=dict(t=10, b=2))
fig.show()

for more details print/display: help(go.layout.Margin)

Hi - we are trying to tidy up the stale issues and PRs in Plotly's public repositories so that we can focus on things that are still important to our community. Since this one has been sitting for several years, I'm going to close it; if it is still a concern, please add a comment letting us know what recent version of our software you've checked it with so that I can reopen it and add it to our backlog. Thanks for your help - @gvwilson
