当我尝试添加另一行时，XSL 0kb

Question

我尝试添加另一行但是当我尝试下载时，该文件的大小为0kb。我的代码有什么错误？我没有编写所有代码，因为它很长。它只是一大堆代码。

<fo:table margin-bottom="10px" table-layout="fixed" border="solid 1px black" width="100%">
                <fo:table-column column-width='=50%' />
                <fo:table-column column-width='50%' />
                <fo:table-body>

                        <fo:table-row keep-with-next.within-page="always" background-color="#DDD">
                                <fo:table-cell border="solid 1px black" number-columns-spanned="3">
                                        <fo:block font-weight="bold" font-size="8pt" margin-top="2px" margin-bottom="2px" text-align="center">
                                                OTHER SERVICES
                                        </fo:block>
                                </fo:table-cell>
                        </fo:table-row>

                        <fo:table-row border="solid 1px black">
                                <fo:table-cell text-align="center" border="solid 1px black" padding="1mm">
                                        <fo:block>
                                                Service/Support
                                        </fo:block>
                                </fo:table-cell>
                                <fo:table-cell text-align="center" border="solid 1px black" padding="1mm">
                                        <fo:block>
                                                Agency
                                        </fo:block>
                                </fo:table-cell>

                              //heres the row I added. How come It began as 0kb?

                                <fo:table-cell text-align="center" border="solid 1px black" padding="1mm">
                                        <fo:block>
                                                Third row
                                        </fo:block>
                                </fo:table-cell>
                        </fo:table-row>
