The "numbered" toggle button for tabular inside tables is misleading — it controls alignment, not numbering #2852
Description
Body
Description:
When the cursor is inside a tabular within a big-table or small-table environment, the focus toolbar shows a "numbered/unnumbered" toggle button (tm_numbered.xpm / 123-style icon) with the tooltip "Toggle numbering". However, this button does not control the table's numbering.
- What users expect: Clicking the "123" button should toggle the table caption between numbered ("表格 1." / "Table 1.") and unnumbered ("表格." / "Table.").
- What actually happens: The button switches between tabular and tabular*, which toggles center alignment of cells, not numbering.
- How numbering actually works: Table numbering is controlled at the outer level by toggling between big-table and big-table* (or small-table / small-table*), which already works correctly.
From TeXmacs/packages/standard/std-markup.ts (line 320):
<assign|tabular*|<macro|body|<tformat|<cwith|1|-1|1|-1|cell-halign|c>|<arg|body>>>>This confirms that tabular* only sets cell-halign to center — it has nothing to do with numbering.
Proposed Fix
Change the icon and/or tooltip of the toggle button in the tabular context so it accurately reflects its actual purpose (cell alignment toggle), rather than appearing as a numbering control.
Context
Discovered during investigation in PR #2833 / issue #2787. As clarified by @Yuki-Nagori, the original issue was based on a misunderstanding of what the button does. The underlying functionality works correctly — only the UI representation is misleading.
