Can I create a sub-table for one certain field?

[mikeo]

The table I've created has a sub-table already, but I'd like to make another
sub-table just for one column. Can I do this? For example, my table is called
projects. It has a sub-table connected called tasks. One of my fields in my
projects table is called project name. In that field or column, I'd like to
add a sub-table called project name list.

It sounds like you are trying to do this working directly in the tables. If
so, stop now!

Access is not a spreadsheet. The things you learned to do in Excel, you'll
need to unlearn, if you want to get good use from Access.

In a relational database like Access, it all starts with the data.

Please describe your "what" (the data you are working with), rather than the
"how" (as in, how you are trying to do something).

Tables - and subtable datasheets - are simply too limited in their
capabilities for what you want to do. They're not really designed for data
interaction; you would do MUCH better to use a Form with two (or three, or
seven) Subforms, along with combo boxes, option groups, and all the other
tools that Forms provide.

Take a look at some of these resources to see how best to make use of the many
tools Access provides:

It sounds more like you are trying to use a lookup table and possibly create a constraint. See if this is what you mean.
Create a new table called ProjectNames with 2 columns, an autonumber called projectnameid and a text column called projectname. Save that and fill the projectname column with your project names. Edit your Projects table, change the datatype for your projectname column to number. At the bottom of the screen in the field properties pane, select Lookup (hence the name). Change the display control type to Combobox, change rowsource type to table/query, select the newly created projectnames table as the rowsource, bound column is one, column count is 2, column widths 0;2. Save the table and switch to datasheet view, instead of typing in a name, you will choose it from a list. This ensures that each project has one and only one name, and those names are selected from a list of names.

Create a new table called ProjectNames with 2 columns,
an autonumber called projectnameid and a text column
called projectname. Save that and fill the projectname
column with your project names. Edit your Projects
table, change the datatype for your projectname column
to number. At the bottom of the screen in the field
properties pane, select Lookup (hence the name). Change
the display control type to Combobox, change rowsource
type to table/query, select the newly created
projectnames table as the rowsource, bound column is
one, column count is 2, column widths 0;2. Save the
table and switch to datasheet view, instead of typing
in a name, you will choose it from a list. This ensures
that each project has one and only one name, and those
names are selected from a list of names.
Hopefully this comes out legible.
