Nested HTML Tables
Nested HTML tables are tables that are placed inside another table. They are used to create more complex and structured layouts with HTML tables. To create a nested table, you need to insert a <table> element inside a <td> element of the outer table.

Table In A Table In A Table
If you want to create a table inside a table inside a table, you can do so by nesting more elements inside the cell elements of the inner tables. We can combine as many tables as we wish.
Use Colspan and Rowspan Instead

Hover the tables and click the pencil icons to inspect their source.
Using colspan and rowspan instead of nested tables can have some advantages, such as:
- Simpler and cleaner HTML code
- Easier to maintain and update
- Better performance and loading speed
- Better accessibility and compatibility with screen readers
- More flexibility and responsiveness with CSS
However, colspan and rowspan can also have some disadvantages, such as:
- Limited to rectangular shapes and alignments
- Cannot span across different table sections (thead, tbody, tfoot)
- Cannot nest other elements inside a spanned cell
- Can cause problems with sorting and filtering data
Therefore, you should use colspan and rowspan when you need to create simple and logical layouts, but avoid using them for complex and irregular layouts that might require nested tables
Nested Div Tables
We can place div tables inside other div tables. This is obvious because we can put <div> tags inside other divs. The online converter at DivTable.com supports converting nested tables to structured divs.
