4.1 advanced tables

  1. 1. Advanced Tables
  2. 2. Spanning Columns and Rows: So far, our tables have been relatively simple, with a uniform grid of rows and columns: XHTML allows us to create more complex table elements by spanning specified rows or columns:
  3. 3. Spanning Columns: <ul><li><table width=&quot;300&quot; border=&quot;1&quot;> </li></ul><ul><li><tr> </li></ul><ul><li><td colspan=&quot;3&quot; >Span 3 Columns</td> </li></ul><ul><li></tr> </li></ul><ul><li><tr> </li></ul><ul><li><td>R2C1</td> </li></ul><ul><li><td>R2C2</td> </li></ul><ul><li><td>R2C3</td> </li></ul><ul><li></tr> </li></ul><ul><li><tr> </li></ul><ul><li><td>R3C1</td> </li></ul><ul><li><td>R3C2</td> </li></ul><ul><li><td>R3C3</td> </li></ul><ul><li></tr> </li></ul><ul><li></table> </li></ul>By adding the colspan=&quot;3&quot; to the <td> element, we are telling the browser that we want to stretch a single table cell across the space of three columns. R3C2 R2C2 R3C3 R3C1 R2C3 R2C1 Span 3 Columns
  4. 4. Spanning Rows: <ul><li><table width=&quot;300&quot; border=&quot;1&quot;> </li></ul><ul><li><tr> </li></ul><ul><li><td rowspan=&quot;3&quot; >Span 3 Rows</td> </li></ul><ul><li><td>R1C2</td> </li></ul><ul><li><td>R1C3</td> </li></ul><ul><li></tr> </li></ul><ul><li><tr> </li></ul><ul><li><td>R2C2</td> </li></ul><ul><li><td>R2C3</td> </li></ul><ul><li></tr> </li></ul><ul><li><tr> </li></ul><ul><li><td>R3C2</td> </li></ul><ul><li><td>R3C3</td> </li></ul><ul><li></tr> </li></ul><ul><li></table> </li></ul>The rowspan=&quot;3&quot; in the <td> element accomplishes the same thing, but stretches a cell across multiple rows instead.
