To make it simpler to align the columns in tables with less wikicode.
Usage
Place {{Table alignment}} just before the table and then add some classes to the table.
classname
Purpose
defaultleft
Align all table cells left by default
defaultcenter
Align all table cells center by default
defaultright
Align all table cells right by default
colNleft
Align the cells in column N left, where N is a number
colNcenter
Align the cells in column N center, where N is a number
colNright
Align the cells in column N right, where N is a number
Limitations
Column numbers up to col19 are supported. A table can have more columns but they cannot be aligned with this method.
On tables using rowspan or colspan, using the classes may not work well on those rows because the alignment appears in wrong cells. Normal table code like style="text-align: left/center/right;"| cell content can be added to individual cells, both to get the wanted alignment and override unwanted alignment.
