Per-column styles

[tyteen4a03]

How can I specify in my column definition the styles I want to apply for the whole column?

You can see in this example how to add a classname or a style to the header and the cell:

You can put a condition like below.

<th {...column.getHeaderProps([{
  className:  cell.column.Header === 'My Header' ? 'myClassName' : '',
  style: cell.column.Header === 'My Header' ? myStyleObject : {},
}])}>
