How to Set Table Column Attributes in HTML

Tables in HTML are used to provide a matrix of rows and columns, with each cell holding its own value. You can set certain formatting attributes for each column independently, such as alignment and width.

Instructions

Difficulty: Moderately Easy

Things You’ll Need:

• Text file editor

Create the Table

1. Open the program with which you're editing your web page. Find the place you want to put the table, then click to insert your cursor.
2. Type the following: .
   Replace the "1" with a number that indicates how thick you want the table's borders to be. Omit the "border" expression and number entirely if you want the borders to be invisible.

   Set Formatting for a Column

   Type the following by itself on the next line to indicate that you are setting attributes for the first column of the table:
   
   Replace "3" with the number of columns that you want these attributes to apply to, counting from the leftmost unformatted column to the right. If you omit the span attribute, the formatting will apply to a single column.
   Replace "right" with "left," "center" or "justify" to reflect the alignment you want the contents of the column to have.
   Replace "top" with "bottom" or "center" to reflect the vertical alignment you want the contents of the column to have.
   Replace "40" with a number that reflects how many pixels wide you want the column to be.
   Write an additional column tag for each additional column in this table for which you want to set attributes. Each column tag operates on the next unformatted column, from left to right.

   Finish the Table
