Grouping Columns in Firefox and Chrome

Exploring the functionality of the <colgroup> tag in a table with 5 columns and a style attribute.

Despite my efforts, I could not get it to function properly on Firefox 3.6/Chrome 5. This led me to search for answers on the w3c website.
After examining the code on the w3c editor, it became clear that even there things were not working as expected. Only IE8 seemed to render it correctly. Opera 10.51 handled the align tag but ignored the style tag. Both ffox and chrome completely disregarded colgroup.

The question arises: What might be the mistake made by myself and w3c? Has colgroup been deprecated without us realizing?

Answer №1

It is important to note that table cells are not considered descendants of the columns they are placed in, as hierarchical data structures do not handle 2 dimensional data effectively.

To delve deeper into this concept, Hixie provides a detailed explanation:

Answer №2

In the world of CSS, restrictions exist on which properties can be applied to cells in columns under the CSS 2.1 Standard due to the fact that cells are not considered true descendants of columns.

While browsers like Firefox adhere strictly to these standards, others may allow a broader range of properties to be effective in styling columns.

For more information, refer to: http://www.w3.org/TR/CSS2/tables.html#columns

If you wish to apply additional properties such as text-align, it is recommended to assign the same class to all cells within the column and then style that particular class accordingly.

Answer №3

To match a specific column in CSS, you can utilize the adjacent sibling selectors. An example of this is:

td + td + td{... apply your styling here ...}
