[Inspect] Better control when there are multiple tables

[nickofthyme]

Describe the feature:

When multiple tables are defined in the visualization, they are shown and named in index order like Table 1 and Table 2. Then when exported they are named as Inspector 1 and Inspector 2. This also applies when there is one a single table but less annoying.

Ideally we could:

• Name the tables
• Provide and show a description of each table
• Provide a sorting order
• Provide a filename for the table when downloaded.
