【问题】

docbook中,已经实现了表格显示:

    <table>
    <title id="mpeg.header_format">MPEG音频的帧头的格式</title>
    <tgroup cols="4">
        <thead>
            <row><entry>位置(bit)</entry><entry>长度(bit)</entry><entry>含义</entry><entry>示例</entry></row>
        </thead>
        
        <tbody>
            <row><entry>0</entry><entry>11</entry><entry>用于同步帧,找到此帧头(所有位均置1)</entry><entry>1111 1111 111</entry></row>
            <row><entry>11</entry><entry>2</entry><entry>MPEG音频的版本ID</entry><entry>11</entry></row>
            <row><entry>13</entry><entry>2</entry><entry>Layer 的索引</entry><entry>01</entry></row>
            <row><entry>15</entry><entry>1</entry><entry>保护位:<literallayout>0 – 用16位的CRC保护下面的帧头
1 – 无CRC</literallayout></entry><entry>1</entry></row>
            <row><entry>16</entry><entry>4</entry><entry>比特率索引 (见下表)</entry><entry>1001</entry></row>
            <row><entry>20</entry><entry>2</entry><entry>采样率索引 (见下表)</entry><entry>11</entry></row>
            <row><entry>22</entry><entry>1</entry><entry>填充位。如果设置了此位,就会对每帧数据填充一个slot (对于帧大小的计算很重要)</entry><entry>0</entry></row>
            <row><entry>23</entry><entry>1</entry><entry>私有位 (仅用于标示性的)</entry><entry>1</entry></row>
            <row><entry>24</entry><entry>2</entry><entry>声道的模式 </entry><entry>01</entry></row>
            <row><entry>26</entry><entry>2</entry><entry>模式扩展 (仅用于联合立体声) (注:此处不是本文重点,故忽略相关的索引表)</entry><entry>00</entry></row>
      </tbody>
    </tgroup>
    </table>

但是编译有warning:

且编译出来的效果也难看:

bad column width

现在想要根据自己的需要,去设置不同的列,不同的宽度。

【解决过程】

1.参考:Column widths,添加了对应代码:

    <table>
    <title id="mpeg.header_format">MPEG音频的帧头的格式</title>
    <tgroup cols="4">
    <colspec colnum="1" colname="col1" colwidth="1*"/>
    <colspec colnum="2" colname="col2" colwidth="1*"/>
    <colspec colnum="3" colname="col3" colwidth="6*"/>
    <colspec colnum="4" colname="col4" colwidth="2*"/>

        <thead>
            <row><entry>位置(bit)</entry><entry>长度(bit)</entry><entry>含义</entry><entry>示例</entry></row>
        </thead>
        
        <tbody>
            <row><entry>0</entry><entry>11</entry><entry>用于同步帧,找到此帧头(所有位均置1)</entry><entry>1111 1111 111</entry></row>
            <row><entry>11</entry><entry>2</entry><entry>MPEG音频的版本ID</entry><entry>11</entry></row>
            <row><entry>13</entry><entry>2</entry><entry>Layer 的索引</entry><entry>01</entry></row>
            <row><entry>15</entry><entry>1</entry><entry>保护位:<literallayout>0 – 用16位的CRC保护下面的帧头
1 – 无CRC</literallayout></entry><entry>1</entry></row>
            <row><entry>16</entry><entry>4</entry><entry>比特率索引 (见下表)</entry><entry>1001</entry></row>
            <row><entry>20</entry><entry>2</entry><entry>采样率索引 (见下表)</entry><entry>11</entry></row>
            <row><entry>22</entry><entry>1</entry><entry>填充位。如果设置了此位,就会对每帧数据填充一个slot (对于帧大小的计算很重要)</entry><entry>0</entry></row>
            <row><entry>23</entry><entry>1</entry><entry>私有位 (仅用于标示性的)</entry><entry>1</entry></row>
            <row><entry>24</entry><entry>2</entry><entry>声道的模式 </entry><entry>01</entry></row>
            <row><entry>26</entry><entry>2</entry><entry>模式扩展 (仅用于联合立体声) (注:此处不是本文重点,故忽略相关的索引表)</entry><entry>00</entry></row>
      </tbody>
    </tgroup>
    </table>

然后编译时,也没了warning了:

Administrator@K470 /cygdrive/e/Dev_Root/docbook/dev/src/docbook/books/VBR/src

$ E:/Dev_Root/docbook/config/tool/fop/fop-1.0/fop.cmd -c E:/Dev_Root/docbook/config/tool/fop/fop-1.0/conf/fop.xconf E:/Dev_Root/docbook/dev/src/docbook/books/VBR/output/fo/MPEG_VBR.fo -pdf E:/Dev_Root/docbook/dev/src/docbook/books/VBR/output/pdf/MPEG_VBR.pdf

警告: Font "ZapfDingbats,normal,700" not found. Substituting with "ZapfDingbats,normal,400".

四月 30, 2012 2:02:13 下午 org.apache.fop.hyphenation.Hyphenator getHyphenationTree

严重: Couldn’t find hyphenation pattern zh_cn

结果出来的表格的宽度,也好看了:

good width

【总结】

在table的tgroup之后,添加对应的colspec,指定对应的colwidth,即可达到自定义表格中列的宽度。
