`ColumnGroup` (component) ========================= Component that defines the attributes of a table column group. Props ----- ### `align` The horizontal alignment of the table cell content. type: `enum('left'|'center'|'right')` ### `fixed` Controls if the column group is fixed when scrolling in the X axis. type: `bool` defaultValue: `false` ### `header` This is the header cell for this column group. This can either be a string or a React element. Passing in a string will render a default footer cell with that string. By default, the React element passed in can expect to receive the following props: ``` props: { height: number // (supplied from the groupHeaderHeight) width: number // (supplied from the Column) } ``` Because you are passing in your own React element, you can feel free to pass in whatever props you may want or need. You can also pass in a function that returns a react elemnt, with the props object above passed in as the first parameter. type: `union(node|func)`
