You can write a macro or use the sendobject command - whichever is more comfortable for you. To write a macro, open the macro tab in Access, and use the SendObject function. You will need to specify the name of the table, the recipients and the format of the attachment.
Then, if necessary, you can create a command button and choose the "run macro" action in the miscellaneous category.
Choose the Macro you just created and label it.
