How to Create Tables in HTML: Simple Steps for Beginners

tag. To make an invisible border, set the border attribute to 0. (Although most browsers default to a table border of 0, specifically stating it ensures that the border will be invisible in all browsers.)

Below are two examples of what this looks like. On the left are the codes for one table with a 2-pixel border and another table with an invisible border. The finished products are on the right.

Here’s a useful trick — design the table with a visible border, which will show you just how your elements are broken up. When you have everything in place, change the border attribute to 0.

Create table layouts

Two attributes for laying out table content were cellpadding and cellspacing. However, in HTML 5, those attributes are no longer supported. That’s not a problem; using the style sheet language Cascading Style Sheets will help. CSS is good to know because it can be used to specify the presentation and styling of a document.

The CSS section in our example starts with and ends at . The wording should be self-explanatory, as the border is set at 2 pixels and is solid black, while the padding is set at 10 pixels. The latter controls the distance (in pixels) between the cell’s contents and its sides.

   table {
      border: 2px solid black;
      border-collapse: collapse;
   }
   td {
      padding: 10px;
   }

Make cells the shape you want

HTML doesn’t stick you with plain grids for your table layout. With the rowspan and colspan attributes of the

tag, you can make a given cell span the height or width of several other cells. To use these attributes, simply assign them a value based on the number of cells you want to span.

For instance, the following table has two rows of three columns each:

Cell contents Cell contents Cell contents

To make the first cell span all three columns, add colspan=”3″ to its

tag and delete the other two tags in that row:

If you’d like to make that first cell span two rows instead, add rowspan=”2″ to its

tag and delete the first tag from the second row:

Of course, you can make your tables far more complex than these examples. If you choose to do so, it’s always a good idea to sketch out your tables before you create them.

Make cells the size you want

Table cells size themselves to their content by default. But what if you want cells of a different size? Enter the width and height attributes of the

tag. Just specify the size in pixels, and you’re all set. To make a cell 100 pixels wide and 80 pixels high, for example, you’d do this:

Note that width and height are only suggested attributes. That is, they take effect only if the cell’s set width or height doesn’t conflict with other cells in the same column or row.

Precisely place cell contents

Once you start changing the shape and size of table cells, the cells no longer shape themselves around their contents. Thus, to place elements where you want within such table cells, you need two attributes of the

tag: align, which places objects left, right, or center within a cell; and valign, which moves them up and down using the top, middle, and bottom instructions. (By default, elements align horizontally to the left and vertically in the middle.) For instance, to align text to the top right in a 100-by-80-pixel cell, you’d use the following code:

Note: when you’re placing objects in table cells, and you want them to align properly, don’t leave space after the opening

or before the closing

of a cell. The cell’s contents should touch the

tags to ensure proper alignment, especially when you’re working with images.

Make your table colorful

Sick of having your table blend in with your page? Then change its background color! It used to be a case of adding the bgcolor attribute to the

tag and assigning it a standard hexadecimal color code or a one-word color name. However, this attribute is no longer supported in HTML 5. That means we turn to CSS again.

For example, this code creates a simple table with a pale blue background:

Not everything has to be black and white. Image: HTML Code Editor


   table {
      background-color: #CCFFFF;
   }
   td {
      padding: 10px;
   }

Place your table on the page

In addition to formatting elements within a table, you can control where your table appears on the page. Two

attributes can help you out:

  • The align attribute aligns the table left, right, or center on the page (left is the default).
  • The width attribute lets you specify a fixed amount of pixels for the table’s width (by using a number, as in
) or lets you make the table occupy a percentage of the browser window’s width (by assigning a percentage, as in

).

Thus, the following code sets up a table 150 pixels wide and centered on the page:

The code below sets up a table three-quarters the width of the browser window, aligned on the right side of the page:

As you can see, with basic knowledge of HTML, tables can be constructed with ease. In fact, when you get more familiar with HTML, you’ll find some of it can be replaced with CSS.
