2.1.105 [CSS-Level2-2009] Section 17.3, Columns

V0161:

The specification states:

 ‘border'
  
 The various border properties apply to columns only if 'border-collapse' is set to 
 'collapse' on the table element. In that case, borders set on columns and column 
 groups are input to the conflict resolution algorithm that selects the border 
 styles at every cell edge.

Quirks Mode and IE7 Mode (All Versions)

The border properties are not supported for columns and column groups; however, both collapsing and separated border modes are supported.

V0162:

The specification states:

 'background' 
  
 The background properties set the background for cells in the column, but only if 
 both the cell and row have transparent backgrounds. See "Table layers and 
 transparency."

Quirks Mode and IE7 Mode (All Versions)

The following variations apply:

  • The background properties of the display table types table-column and table-column-group are not supported

  • The table-column and table-column-group values of the display property are not supported.

V0163:

The specification states:

 'visibility'
  
 If the 'visibility' of a column is set to 'collapse', none of the cells in the 
 column are rendered, and cells that span into other columns are clipped. In 
 addition, the width of the table is diminished by the width the column would have 
 taken up. See "Dynamic effects" below. Other values for 'visibility' have no 
 effect. 

Quirks Mode and IE7 Mode (All Versions)

The visibility property is not supported for columns and column groups.
