Multiple Tables

Heading-based tab labels: Use the Markdown heading immediately above each table as the tab name. Configure with markdownTableEditor.tabLabelMode ("number" for "Table 1, 2…" or "heading" for heading names). Multiple tables under the same heading are distinguished with (1), (2) suffixes

Tab tooltips: Long tab labels are truncated with …; hovering for 1 second shows the full label in a tooltip
