Reviewer's guide (collapsed on small PRs)

Reviewer's Guide

Adds a null check before accessing a table row header's classList during column resize logic to prevent JavaScript errors when IsDetails is true.

File-Level Changes

Change	Details	Files
Guard table resize logic against null header elements to avoid runtime errors when computing widths for fixed columns.	Update the resize listener loop to verify the retrieved row child element is not null before checking its CSS classes. Ensure resizeNextFixedColumnWidth is only invoked when a valid header element exists and has the 'fixed' class.	src/BootstrapBlazor/Components/Table/Table.razor.js

Assessment against linked issues

Issue	Objective	Addressed	Explanation
#7802	Prevent the JavaScript runtime error ('Cannot read properties of null (reading "classList")') when the Table component has both AllowResizing="true" and IsDetails="true" enabled.	✅
#7802	Ensure column resizing logic in Table.razor.js safely handles rows where the target cell may be null, without breaking the resizing behavior.	✅
