Take a 5 x 3 subplot layout as follows:

    fig = make_subplots(rows=5, cols=3,
                        specs=[[{'secondary_y': True}, {'secondary_y': False}, {'type': 'table'}],
                               [{'secondary_y': False}, {'secondary_y': False}, {'secondary_y': False}],
                               [{'secondary_y': False}, {'secondary_y': False}, {'secondary_y': False}],
                               [{'secondary_y': False}, {'secondary_y': False}, {'secondary_y': False}],
                               [{'secondary_y': False}, {'secondary_y': False}, {'secondary_y': False}]],
                        shared_xaxes=True, shared_yaxes=True,
                        vertical_spacing=0.01, horizontal_spacing=0,
                        row_heights=[0.775, 0.15, 0.025, 0.025, 0.025], column_widths=[0.8, 0.1, 0.1])

We add subplots as follows:

fig.add_trace(go.Scatter(x= ... row=1, col=1)
fig.add_trace(go.Scatter(x= ... row=1, col=2)
fig.add_trace(go.Scatter(x= ... row=2, col=1)
fig.add_trace(go.Scatter(x= ... row=3, col=1)
fig.add_trace(go.Scatter(x= ... row=4, col=1)
fig.add_trace(go.Scatter(x= ... row=5, col=1)

At position row=1 col=3 we place a table.

fig.add_trace(go.Table(header=dict(line=dict(color='red'),
                              fill=dict(color='red')),
                       cells=dict(values=[df.A, df.B])),
              row=1, col=3)

This all works fine. But when we add an hline or vline to the top left graph...

        fig.add_vline(x=42, line_width=1, line_dash='dot', line_color='rgba(255, 165, 0, 0.3)', row=1, col=1)

Plotly throws an error:

_plotly_utils.exceptions.PlotlyKeyError: Invalid property specified for object of type plotly.graph_objs.Table: 'xaxis'

Did you mean "cells"?

This happens regardless of line orientation (h or v), or if the lines are limited to a single row and col or spanning all cols.

Posting in in case this may be a bug.
Posted also on StackOverflow, where Rob Raymond prepared a working example and also a workaround for this issue.

Reproduce the 5 x 3 mixed graph-and-table layout from the issue, then add the shown fig.add_vline call and compare it with the working case. Start by tracing make_subplots and the hline/vline handling around table subplots. Done means both hline and vline render for graph subplots without raising a PlotlyKeyError for the Table trace.
