当我用Microsoft excel打开下载的文件时,它只显示第一轮,LibreOffice显示所有现有的13轮。事实上,我很惊讶LibreOffice可以显示它,因为根据,它说一个表元素只有一个实例对单个工作表有效。:
.....
<xsd:element name="Table" type="TableType" minOccurs="0">
<xsd:annotation>
<xsd:documentation>Defines the table to contain the cells of the current worksheet. Only one instance of a Table element is valid for a single worksheet.</xsd:documentation>
</xsd:annotation>
</xsd:element>
.....
。。。。。
定义包含当前工作表单元格的表。一个表元素只有一个实例对单个工作表有效。
.....
因此,我建议您只打印一个表元素中的行,如下所示:
<Table>
<% @tours.each_with_index do |tour, index| %>
<Row></Row>
<Row>
<Cell><Data ss:Type="String"><%= "Tour #{index + 1}" %></Data></Cell>
</Row>
<Row>
<Cell><Data ss:Type="String">#</Data></Cell>
<Cell><Data ss:Type="String">Pilot Name</Data></Cell>
<Cell><Data ss:Type="String">Pilot Country</Data></Cell>
</Row>
<% tour.pilots.each_with_index do |pilot, index| %>
<Row>
<Cell><Data ss:Type="Number"><%= index + 1 %></Data></Cell>
<Cell><Data ss:Type="String"><%= pilot.name %></Data></Cell>
<Cell><Data ss:Type="String"><%= pilot.country.name %></Data></Cell>
</Row>
<% end %>
<% end %>
</Table>
<% @tours.each_with_index do |tour, index| %>
<Worksheet ss:Name="<%= "Tour #{index + 1}-Sheet" %>">
<Table>
<Row></Row>
<Row>
<Cell><Data ss:Type="String"><%= "Tour #{index + 1}" %></Data></Cell>
</Row>
<Row>
<Cell><Data ss:Type="String">#</Data></Cell>
<Cell><Data ss:Type="String">Pilot Name</Data></Cell>
<Cell><Data ss:Type="String">Pilot Country</Data></Cell>
</Row>
<% tour.pilots.each_with_index do |pilot, index| %>
<Row>
<Cell><Data ss:Type="Number"><%= index + 1 %></Data></Cell>
<Cell><Data ss:Type="String"><%= pilot.name %></Data></Cell>
<Cell><Data ss:Type="String"><%= pilot.country.name %></Data></Cell>
</Row>
<% end %>
</Table>
</Worksheet>
<% end %>

或者您可以将它们放入不同的工作表中,如下所示:
<Table>
<% @tours.each_with_index do |tour, index| %>
<Row></Row>
<Row>
<Cell><Data ss:Type="String"><%= "Tour #{index + 1}" %></Data></Cell>
</Row>
<Row>
<Cell><Data ss:Type="String">#</Data></Cell>
<Cell><Data ss:Type="String">Pilot Name</Data></Cell>
<Cell><Data ss:Type="String">Pilot Country</Data></Cell>
</Row>
<% tour.pilots.each_with_index do |pilot, index| %>
<Row>
<Cell><Data ss:Type="Number"><%= index + 1 %></Data></Cell>
<Cell><Data ss:Type="String"><%= pilot.name %></Data></Cell>
<Cell><Data ss:Type="String"><%= pilot.country.name %></Data></Cell>
</Row>
<% end %>
<% end %>
</Table>
<% @tours.each_with_index do |tour, index| %>
<Worksheet ss:Name="<%= "Tour #{index + 1}-Sheet" %>">
<Table>
<Row></Row>
<Row>
<Cell><Data ss:Type="String"><%= "Tour #{index + 1}" %></Data></Cell>
</Row>
<Row>
<Cell><Data ss:Type="String">#</Data></Cell>
<Cell><Data ss:Type="String">Pilot Name</Data></Cell>
<Cell><Data ss:Type="String">Pilot Country</Data></Cell>
</Row>
<% tour.pilots.each_with_index do |pilot, index| %>
<Row>
<Cell><Data ss:Type="Number"><%= index + 1 %></Data></Cell>
<Cell><Data ss:Type="String"><%= pilot.name %></Data></Cell>
<Cell><Data ss:Type="String"><%= pilot.country.name %></Data></Cell>
</Row>
<% end %>
</Table>
</Worksheet>
<% end %>
