        Preserve the current paging/sort status across session. The default is false (do not use sessions). Note that
        for this to work properly you need to assign to each table in your application a different id.

      Displays a property of a row object inside a table. MUST be nested inside of a Table tag. The value displayed will
      be the results of a decorator (if any); else the property named by the 'property' attribute; or if the 'property'
      attribute is null, then the results of evaluating the JSP body of the tag.

        name of the property in the bean specified in the parent table tag (via the "name" attribute) which will be used

      <description>
        Resource key used to lookup the title value. Only works if "title" is not defined. Works together with a
        configured I18nResourceProvider, specified via the displaytag.properties file. By default, if JSTL is available,
        the JSTL provider is used, which makes this attribute work the same as fmt:message's key property.

        By default, null values don't appear in the list. By setting 'nulls' to 'true', then null values will appear as
        "null" in the list (mostly useful for debugging). Defaults to 'false'.

      <description>
        Use this attribute to keep a column from being output during an export. The column will only render for the
        named media type(s) - it won't be added to the table if the current request media is not supported. Can be any
        space separated combination of 'html', 'csv', 'xml', 'all', or 'excel'. Defaults to 'all'. See the export page
        in the example webapp for more details.

        The base URL used to construct the dynamic link. If this attribute is provided, then the data that is shown for
        this column is wrapped inside a <a href=""> tag with the url provided through this attribute. Typically you
        would use this attribute along with one of the struts-like param attributes (param*) to create a dynamic link so
        that each row creates a different URL based on the data that is being viewed. An empty href value will generate
        a link to the current page, preserving parameters just like for paging links.]]>

      <description>
        The name of the request parameter that will be dynamically added to the generated href URL. The corresponding
        value is defined by the paramProperty and (optional) paramName attributes, optionally scoped by the paramScope
        attribute.

      <description>
        The name of a JSP bean that is a String containing the value for the request parameter named by paramId (if
        paramProperty is not specified), or a JSP bean whose property getter is called to return a String (if
        paramProperty is specified). The JSP bean is constrained to the bean scope specified by the paramScope property,
        if it is specified. If paramName is omitted, then it is assumed that the current object being iterated on is the
        target bean.

      <description>
        The name of a property of the current object being iterated on, whose return value will be used as the value of
        the parameter (named by the paramId attribute) that will be dynamically added to this href URL. If paramName is
        also specified the property will not be fetched from the object being iterated on, but from the bean specified
        by paramName. The support of paramProperty in conjunction with paramName will be probably removed in future: use
        paramProperty only if you need a property in the iterated object, elsewhere use only paramName (you can select a
        property using an expression name.property).

        paramName attribute. If not specified, all scopes are searched. If paramName is not provided, then the current
        object being iterated on is assumed to be the target bean.
