Hi All,

I am trying to make a table or grid whose column widths will automatically adjust based on the contents. Here is a snippet of my report where I am trying both a grid and table to see what happens.

In both cases, I have just one row, two columns. I am finding that the columns are always 50% each, with the longest column wrapping its content instead of what I expect - the left column should be narrow and the right column be wider, because they don't need to wrap.

 <table id="258">
     <column id="268"/>
     <column id="269"/>
     <header>
         <row id="259">
             <list-property name="visibility">
                 <structure>
                     <property name="format">all</property>
                     <expression name="valueExpr" type="javascript">true</expression>
                 </structure>
             </list-property>
             <cell id="260"/>
             <cell id="261"/>
         </row>
     </header>
     <detail>
         <row id="262">
             <property name="style">Heading</property>
             <property name="textAlign">center</property>
             <cell id="263">
                 <data id="270">
                     <property name="resultSetColumn">Business Unit 1</property>
                 </data>
             </cell>
             <cell id="264">
                 <data id="271">
                     <property name="resultSetColumn">Service Name 1</property>
                 </data>
             </cell>
         </row>
     </detail>
     <footer>
         <row id="265">
             <list-property name="visibility">
                 <structure>

             <cell id="266"/>
             <cell id="267"/>
         </row>
     </footer>
 </table>
 <grid id="59">
     <property name="whiteSpace">pre</property>
     <column id="60"/>
     <column id="61"/>
     <row id="62">
         <cell id="63">
             <property name="style">Heading</property>
             <property name="fontSize">20px</property>
             <property name="paddingTop">2px</property>
             <property name="textAlign">center</property>
             <data id="65">
                 <property name="resultSetColumn">Business Unit 1</property>
             </data>
         </cell>
         <cell id="64">
             <property name="style">Heading</property>
             <property name="fontSize">20px</property>
             <property name="paddingTop">2px</property>
             <property name="textAlign">center</property>
             <data id="66">
                 <property name="resultSetColumn">Service Name 1</property>
             </data>
         </cell>
     </row>
 </grid>



Any suggestions would be appreciated!

Here is a simpler example. I get the same result irrespective of setting report layout preference to "Auto Layout" or "Fixed Layout".

With this code:

<cell id="43">
    <grid id="276">
        <column id="277"/>
        <column id="278"/>
        <column id="279"/>
        <row id="280">
            <cell id="281">
                <property name="borderBottomStyle">solid</property>
                <property name="borderBottomWidth">medium</property>
                <property name="borderLeftStyle">solid</property>
                <property name="borderLeftWidth">medium</property>
                <property name="borderRightStyle">solid</property>
                <property name="borderRightWidth">medium</property>
                <property name="borderTopStyle">solid</property>
                <property name="borderTopWidth">medium</property>

So, the auto layout doesn't help at all? Would you be opposed to scripting to get the look you're wanting?
