What should be avoided when using nested tables?
• When using nested tables, content developers should avoid specifying the parent table width as a percentage when the child table widths are given explicit dimensions. Because there are devices with different screen sizes, percentages will not always represent the same number of pixels. Therefore it is recommended that absolute widths (pixels) be used for both parent and nested tables, to ensure that the content will be rendered properly. Care should be taken to ensure that the total table width is the same as the sum of the widths of the individual columns plus borders and cell spacing. In general, as table nesting levels increase, so does the complexity of the page and the required processing time to display the page. In order to ensure the timely display of pages, very deeply nested tables should be avoided. For some models, a hard limit of 7 is imposed on the table nesting depth.
