Help:Wiki University HTML-- Tables - Widths

Table width
This is our table from the last chapter: {| style="border:1px solid red ; width: 100% " Here is our little table with the width attribute installed:
 * You will notice that the width is being controlled by the size and amount of text in the cells.
 * What if you want the table to be as wide as the page, here we use our width attribute.
 * Let's say we want it to cover the entire width or 100% of the page.
 * We only need to add the width attribute to our opening table tag:
 * PLEASE NOTICE the semi-colon that separates the border attribute from the width attribute. Remember we always use semi-colons to separate attributes.

Cell and column width

 * The width of the cells is controlled by the text or the amount of text in the cells. The width attribute for the entire table does not make the cells equal in width.  If one cell had a large amount of text in it, the other cells might be much smaller in width then in our example.
 * To control the width of cells or actually the columns, we need to install the width attribute in the top cells in each column. If you are wondering why not in all cells like the border attribute, it is because the top cells seem to be able to influence the cells under it.
 * Let's make our table so each of the cells is 25% of the entire width of the table in other words make all the columns the same width.

Here's the coding:


 * AGAIN NOTICE we are determining the width of the columns not just the width of the top row of cells.
 * NOTICE the width attribute is separated from the border attribute by a semi-colon.

 Exercises
 * With our above table place a green border, "inset" style and 25 pixels wide.
 * Make the table 90% in width.
 * Next place a 1 pixel green border around the cells in the first row.
 * Make the first column 35 percent width, the second 15%, the third 25% and let the last column determine its own width.
