2.3.5.4 Timeline Styles

Timeline styles specify the formatting to apply to visual components of Timeline views. The style attribute of the CT_Timeline element specifies the Timeline style to be applied. A Timeline style can be either built-in or user-defined. Built-in Timeline styles are specified in the CT_Timeline element. User-defined Timeline styles are specified in the CT_TimelineStyles element.

A Timeline style is an extension of a table style ([ISO/IEC29500-1:2016] section 18.8) with additional table style elements specific to the formatting of Timeline views. A user-defined Timeline style is specified by a CT_TimelineStyle element and the table style it references.

A user-defined Timeline style consists of the table style elements from the referenced table style and table style elements specified by a group of CT_TimelineStyleElement elements.

The TimelineStyleElements element of a CT_TimelineStyle element specifies the Timeline-style-specific table style elements of the Timeline style. The name attribute of the CT_TimelineStyle element references the user-defined table style that specifies the Timeline-style-specific table style elements of the Timeline style.
