Table row not stretching to 100% width

I am hiding and showing a table row on click of an anchor, but when the tr is shown next time, it does not stretches to it's full length. Here is the demo

Note: go to View Differences and click on envVariable

Here is my code

 var dummy1='<list>  <TagResult elementname="osname" subCategory="system" value1="Linux" value2="HP-US1000" isEqual="false"/>  <TagResult elementname="hostname" subCategory="system" value1="estilo" value2="benz" isEqual="false"/>  <TagResult elementname="release" subCategory="system" value1="2.6.18-128.el5" value2="B.11.23" isEqual="false"/><TagResult elementname="version" subCategory="system" value1="Red Hat Enterprise Linux Server release 5.3 (Tikanga)" value2="U" isEqual="false"/>  <TagResult elementname="machine" subCategory="system" value1="x86_64" value2="ia64 hp server rx2600" isEqual="false"/>  <TagResult elementname="bitmode" subCategory="system" value1="64" value2="64" isEqual="true"/>  <TagResult elementname="numberofcpu" subCategory="system" value1="4" value2="2" isEqual="false"/>  <TagResult elementname="cpuspeed" subCategory="system" value1=" 1862.890" value2="1400" isEqual="false"/>  <TagResult elementname="maxfilesperproc" subCategory="system" value1="32" value2=" 32" isEqual="true"/>  <TagResult elementname="maxthreadsperproc" subCategory="system" value1="2000000" value2="                    256  " isEqual="false"/><TagResult elementname="mempagesize" subCategory="system" value1="4096" value2="4096" isEqual="true"/><TagResult elementname="ssaname3webserviceserver" subCategory="product" value1="ssasvck&gt; Attempt 1 at server &apos;null:-1&apos;ssasvck&gt; Server&apos;null:-1&apos; is down" value2="ssasvck&gt; Attempt 1 at server &apos;null:-1&apos;ssasvck&gt; Server &apos;null:-1&apos; is down" isEqual="true"/><TagResult elementname="TERM" subCategory="envVariable" value1="xterm " value2="xterm" isEqual="true"/><TagResult elementname="JAVA_HOME" subCategory="envVariable" value1="/home/hqusers1/IIR_1152825121_estilo_9.0.1SP2_32 " isEqual="false"/><TagResult elementname="SSANUL" subCategory="envVariable" value1="/dev/null " value2="/dev/null" isEqual="true"/><TagResult elementname="SSA_LIHOST" subCategory="envVariable" value1="estilo:45682 " value2="benz:7660" isEqual="false"/><TagResult elementname="SSH_CLIENT" subCategory="envVariable" value1="10.65.6.131 4760 22 " value2="10.65.241.204 367222" isEqual="false"/></list>';

The default value of a tr's display property is table-row and not block. It should be toggling between none and table-row instead. See http://jsfiddle.net/aQPZk/

This is a problem with your display property.

Change:

       $(".differentEnvironmentHiddentr").css({"display":"block"});

To:
       $(".differentEnvironmentHiddentr").css({display:""});

• The TR is not a block element - by setting it as such, the browser is conforming to the proper box-model specs
• You could set it to table-row as Gustav has suggested, but the easiest way is not to set the display property at all using a blank string (shown above). This would leave the browser to use its default settings/behavior.
