Try setting ENV['GEM_HOME'] before requiring rubygems.  Also, I don't
think you require html-table, I think it's html/table.

C:\myapp>gem install html-table -i gem
Building native extensions.  This could take a while...

C:\myapp>cat foo.rb

 # $LOAD_PATH << File.expand_path( File.dirname( __FILE__ ) + '/gem' )
 ENV['GEM_HOME'] = './gem'
 require 'rubygems'
 require 'html/table'
 include HTML

 Table.html_case = "lower"
 Table::Row.end_tags = false
 Table::Row::Data.end_tags = false
 table = Table.new
 tr1 = Table::Row.new
 tr2 = Table::Row.new
 tr3 = Table::Row.new
 tr1.content = "foo", "bar", "baz"
 tr2.content = 1, 2, 3
 tr3.content = %w/hello world/
 table.push( tr1, tr2, tr3 )
 table[0][1].align = "left"
 puts table.html

C:\myapp>ruby foo.rb
<table>
   <tr>
      <td>foo
      <td align='left'>bar
      <td>baz
   <tr>
      <td>1
      <td>2
      <td>3
   <tr>
      <td>hello
      <td>world
</table>

C:\myapp>
