fix(data-table): fix cell misalignment when using ellipsis.lineClamp

[c01dwave]

Description

Fix cell misalignment in NDataTable when using ellipsis.lineClamp on columns.

Closes #7345

Problem

When a column has ellipsis.lineClamp configured, the cells (both th and td) in that column appear taller than cells in other columns, causing visual misalignment.

Root Cause

The .n-ellipsis--line-clamp class uses display: -webkit-inline-box for multi-line text truncation. As an inline-level box, its default vertical-align: baseline causes inconsistent height calculation compared to regular inline elements in adjacent columns.

Solution

Add vertical-align: middle to .n-ellipsis--line-clamp within data-table-th and data-table-td to ensure consistent vertical alignment.

Changes

• [src/data-table/src/styles/index.cssr.ts]: Added vertical-align: middle style override for .n-ellipsis--line-clamp inside table header and body cells.
