Just include the file containing your table (or whatever) in the project,
then on the properties tab set "Build Action" to "Embedded Resource".
You can then use something like this to access your file as a stream:
Assembly ass = Assembly.GetExecutingAssembly();
string[] resourceNames = ass.GetManifestResourceNames();
foreach (string resourceName in resourceNames)
{
if (resourceName.ToLower().EndsWith(".xml")) // or whatever
{
Stream resourceStream = ass.GetManifestResourceStream(resourceName);
....
