It is similar to your table     lt table border 1 width 50  gt   lt tr gt       lt td rowspan  2  gt x lt  td gt        lt td colspan  4  gt y lt  td gt   lt  tr gt   lt tr gt       lt td bgcolor  FFFF00  gt I lt  td gt       lt td gt II lt  td gt       lt td bgcolor  FFFF00 gt III lt  td gt       lt td gt IV lt  td gt   lt  tr gt   lt tr gt       lt td gt empty lt  td gt       lt td bgcolor  FFFF00 gt 1 lt  td gt       lt td gt 2 lt  td gt       lt td bgcolor  FFFF00 gt 3 lt  td gt       lt td gt 4 lt  td gt   lt  tr gt

Use rowspan if you want to extend cells down and colspan to extend across

User · Answer

You can use rowspan  n  on a td element to make it span n rows  and colspan  m  on a td element to make it span m columns   Looks like your first td needs a rowspan  2  and the next td needs a colspan  4

Colspan and Rowspan A table is divided into rows and each row is divided into cells  In some situations we need the Table Cells span across  or merged  more than one column or row  In these situations we can use Colspan or Rowspan attributes   Colspan The colspan attribute defines the number of columns a cell should span  or merge  horizontally  That is  you want to merge two or more Cells in a row into a single Cell    lt td colspan 2  gt     How to colspan     lt html gt   lt body  gt       lt table border 1  gt           lt tr gt               lt td colspan 2  gt                  Merged              lt  td gt           lt  tr gt           lt tr gt               lt td gt                  Third Cell              lt  td gt               lt td gt                  Forth Cell              lt  td gt           lt  tr gt       lt  table gt   lt  body gt   lt  html gt    Rowspan The rowspan attribute specifies the number of rows a cell should span vertically  That is   you want to merge two or more Cells in the same column as a single Cell vertically    lt td rowspan 2  gt    How to Rowspan     lt html gt   lt body  gt       lt table border 1  gt           lt tr gt               lt td gt                  First Cell              lt  td gt               lt td rowspan 2  gt                  Merged              lt  td gt           lt  tr gt           lt tr gt               lt td valign middle gt                  Third Cell              lt  td gt           lt  tr gt       lt  table gt   lt  body gt   lt  html gt

If you re confused how table layouts work  they basically start at x 0  y 0 and work their way across  Let s explain with graphics  because they re so much fun   When you start a table  you make a grid  Your first row and cell will be in the top left corner  Think of it like an array pointer  moving to the right with each incremented value of x  and moving down with each incremented value of y   For your first row  you re only defining two cells  One spans 2 rows down and one spans 4 columns across  So when you reach the end of your first row  it looks something like this      lt table gt       lt tr gt           lt td rowspan  2  gt  lt  td gt           lt td colspan  4  gt  lt  td gt       lt  tr gt   lt  table gt    Now that the row has ended  the  array pointer  jumps down to the next row  Since x position 0 is already taken up by a previous cell  x jumps to position 1 to start filling in cells    See note about difference between rowspans   This row has four cells in it which are all 1x1 blocks  filling in the same width of the row above it      lt table gt       lt tr gt           lt td rowspan  2  gt  lt  td gt           lt td colspan  4  gt  lt  td gt       lt  tr gt       lt tr gt           lt td gt  lt  td gt           lt td gt  lt  td gt           lt td gt  lt  td gt           lt td gt  lt  td gt       lt  tr gt   lt  table gt    The next row is all 1x1 cells  But  for example  what if you added an extra cell  Well  it would just pop off the edge to the right      lt table gt       lt tr gt           lt td rowspan  2  gt  lt  td gt           lt td colspan  4  gt  lt  td gt       lt  tr gt       lt tr gt           lt td gt  lt  td gt           lt td gt  lt  td gt           lt td gt  lt  td gt           lt td gt  lt  td gt       lt  tr gt       lt tr gt           lt td gt  lt  td gt           lt td gt  lt  td gt           lt td gt  lt  td gt           lt td gt  lt  td gt           lt td gt  lt  td gt           lt td gt  lt  td gt       lt  tr gt   lt  table gt      But what if we instead  rather than adding the extra cell  made all these cells have a rowspan of 2  The thing you need to consider here is that even though you re not going to be adding any more cells in the next row  the row still must exist  even though it s an empty row   If you did try to add new cells in the row immediately after  you d notice that it would start adding them to the end of the bottom row      lt table gt       lt tr gt           lt td rowspan  2  gt  lt  td gt           lt td colspan  4  gt  lt  td gt       lt  tr gt       lt tr gt           lt td gt  lt  td gt           lt td gt  lt  td gt           lt td gt  lt  td gt           lt td gt  lt  td gt       lt  tr gt       lt tr gt           lt td rowspan  2  gt  lt  td gt           lt td rowspan  2  gt  lt  td gt           lt td rowspan  2  gt  lt  td gt           lt td rowspan  2  gt  lt  td gt           lt td rowspan  2  gt  lt  td gt       lt  tr gt       lt tr gt           lt td gt  lt  td gt       lt  tr gt   lt  table gt    Enjoy the wonderful world of creating tables
