This is a template that helps create vertically oriented column headers in tables. It even works for sortable columns.
Although this template was made with table headers in mind, it can work with regular cells as well.
If the header cells have other attributes, for example, colspan or rowspan, there must be no vertical bar | between the attributes and the template call.
Parameter list
1 – The desired text; can contain wikilinks ([[]]). You can escape the equals sign either by using {{}} or by explicitly mentioning the 1= parameter.
nb – Give any non-empty value in order to apply a {{nobold}} template to the text.
va – Vertical alignment (bottom, top, middle). Default is bottom.
stp – Give any non-empty value in order to apply a top padding to the cell (useful if the header is bottom-aligned; required for sortable columns).
mw – Manual width; override the default value, which was automatically generated based on the number of line breaks (you can use <br>, <BR /> or any other combination).
style – Additional styles for the <div/> containing the rotated text. May contain double quotes.
cellstyle – Additional styles for the entire cell. May contain double quotes. Use this instead of the cell's style attribute. Use background-color instead of background if you need it for the header of a sortable column.
Examples
! {{vert header|Your text here}} – basic example
! {{vert header|nb=1|stp=1|Your text here}} – produces an explicitly sortable, no-bold, sortable header
! {{vert header|va=top|Your text here}} – produces an unsortable, top-aligned table header
! colspan="2" {{vert header|cellstyle=background-color:gold|Your text here}} – produces an unsortable header spanning two columns, with a gold background; use no vertical bar after colspan
You can also use the ! {{verth|Your text here}} shorthand.
