* ```php
* [
* [0, 2], [3, 6]
* ]
* ```
* - `content`: `array`, header content for each column. You must set this as `$key => $value`, where `$key` is the
* zero based index for the column, and `$value` is the content to display for the column. The `$value` can take in
* special function names to summarize values for the column. If set to one of [[GridView::F_COUNT]],
* [[GridView::F_SUM]], [[GridView::F_AVG]], [[GridView::F_MAX]], [[GridView::F_MIN]], the values will be auto summarized.
* - `contentFormats`: `array`, header content formats for each column. This is only applicable currently only for
* number type or a custom type using a javascript callback. You must set this as `$key => $value`, where
* `$key` is the 0 based index for the column, and `$value` is the format settings for the column. The
* `$value` is a format specification setup as an array containing one or more of the following options:
* - `format`: string, whether `number` or `callback`
* - `decimals`: number, number of decimals (for number format only)
* - `decPoint`: string, decimals point character (for number format only). Defaults to `.`.
* - `thousandSep`: string, thousands separator character (for number format only). Defaults to `,`.
* - `func`: string, the javascript callback function name (for callback format only). This should be set to a
* globally accessible javascript function name. For example if you set this to `customCallback`, the function
* should be of the signature: `function customCallback(source, data) { return custom_convert(source, data);}`.
* The parameters for the callback function that will be passed are:
* - `source`: string, the summary column source as set in `content` section if available
* - `data`: `array`, the text values of each of the child columns in this group.
* An example of setting the `content`:
* ```php
* [
* 7 => ['format'=>'callback', 'func'=>'customCallback']
* 8 => ['format'=>'number', 'decimals'=>2, 'decPoint'=>'.', 'thousandSep'=>',']
* ]
* ```
* - `contentOptions`: `array`, header HTML attributes for each column. You must set this as `$key => $value`, where
* `$key` is the 0 based index for the column, and `$value` is the HTML attributes to apply for the column. The
* `$value` must be an array of HTML attributes for the table column. An example of setting the `contentOptions`:
* ```php
* [
