Summary by Sourcery

Enable and improve support for the OnAutoFitContentAsync callback in the Table component, using the callback's returned width when provided and falling back to automatic cell measurement otherwise.

Enhancements:

• Register AutoFitContentCallback only when OnAutoFitContentAsync is set to avoid null callback calls
• Guard the JavaScript AutoFitContent callback invocation and initialize width from its return value
• Fall back to measuring cell widths only if the callback returns zero

Reviewer's guide (collapsed on small PRs)

Reviewer's Guide

Enhances the table component’s auto-fit feature by making the OnAutoFitContentAsync callback optional and using its returned width as the initial measurement before falling back to DOM-based width calculations.

-        const cell = row.cells[index];
-        maxWidth = Math.max(maxWidth, calcCellWidth(cell));
-    });
+    let maxWidth = widthValue;
+    if (maxWidth === 0) {

</code_context>

<issue_to_address>
**issue (bug_risk):** Initial maxWidth assignment may cause issues if widthValue is negative.

If widthValue is negative, maxWidth will remain invalid since the recalculation is skipped. Check for widthValue > 0 to ensure only valid widths are used.
</issue_to_address>
