DOM Rendering Performance

Fixed table layouts improve rendering performance with large tables by: 1) Enabling the browser to calculate column widths based on the first row only, rather than analyzing all content, 2) Reducing the number of layout recalculations needed, 3) Allowing for more efficient rendering of subsequent rows, 4) Minimizing reflows when content changes. Implementation techniques include: - Using table-layout: fixed - Specifying explicit column widths - Using virtual scrolling for large datasets - Minimizing dynamic content updates This is particularly important for tables with many rows or frequent content updates.
