Editing cells
So far we learned how to make changes to the captions and headings of our table. In addition, we can do all the same things to cells, that is:
 * We can change the size of the font with the font-size attribute.
 * We can change the font with the font-family attribute.
 * We can change the style of font with our bold and italic tags. (using the 'mark)
 * We can change the background color of the cells.
 * We can add padding around the text in the cells.
 * For these attributes to apply, it requires them to be placed into every cell

Here is the example of all of the above possibilities for each cell, with a change of font-size, font-family, background color along with some padding.

Here is the code for all of the changes we made to the cells for Apple, Peas and Peanuts

 | style=" border:  1px solid red ; width:25%; font-family:Rockwell; font-size:20px; text-align:center; background-color:lightblue" | Apples"  | style="border:1px solid red; width:25%" |  Peas    | style="border:1px solid red; width:25%" |  Peanuts 

Cell padding

 * We will use this table for our demonstrations: Example 1---Padding in only one cell


 * NOTICE Putting padding in the first cell Apples is the only cell to move over the 10px, the other cells are not affected by the coding. To move the text over in the other cells, padding must be put into each individual cell.
 * NOTICE However the padding increased the over all height of the row.


 * Let's add 10 pixels of padding to the first row of cells: Example 2

Here is the coding:
 * NOTICE how all the cells in the row have expanded.


 * When applying padding to column labels, you only have to put the padding attribute in the first cell of the row to affect all the cells in the row.


 * NOTICE you can also center text in each cell by placing the text within tags.

Cell separation
Another way to create space between material in cells is to place a space between the cells themselves.
 * This requires the border-spacing attribute: border-spacing: 3px.
 * This attribute can only be added to the opening table tag . Here is what our table will look like with a cell separation of 3 pixels:

Here is the coding: 


 * However, if you are changing text for the entire row, there is another way.
 * See the next chapter after you have completed the exercises and quick quiz below.

Eliminate border spacing
If we want to have the individual cells with their borders up against each other, we use the border-collapse:collapse attribute. This coding goes only in the table tag.

Here is the coding.  {| style=" border:1px solid red ; width:70%; border-collapse:  collapse"

Our table would look like this if we used this attribute:

Try these out


 Exercises
 * With our above table place a black border, "dotted" style and 5 pixels thick.
 * Make the table 600 pixels wide.
 * Next place a blue border around all the cells.
 * Place 5 pixels of padding in the header row of cells
 * Separate all the cells with 5 pixels.
 * Place a lightblue background on the column headers.
