Subtable: Editable part of an array

The purpose of SubTable is to provide the user an alternative editable view of part of an edit table. If a variable a is defined as an edit table, a variable b defined as SubTable(a[i = x]) lets the user use u to view and edit a subarray of a, for which index i of a has value x. Any change you make to cells of b is reflected in a, and vice versa. The actual values are stored in edit table a.

SubTable(a[i = x]): A subtable can also show subarrays of a in a different order, if x is an array containing some or all values of i in a different sequence. b can also use different number formats.

A subtable also works if a is defined using any editable table functions, including edit table (table), probability table (probtable), deterministic table (determtable), or even another subtable.

SubTable() must be the main expression in the definition of a variable. It cannot be a subexpression or inside a function. Its parameter must be a slice or subscript operator. For example, in the simplest form:

SubTable(a[i = x])

where x is an element of index i and x is a value of i. Many other variations are also useful including:

SubTable(a[i = x])
SubTable(a[i = x, j = y])
SubTable(a[i = b])
SubTable(a[@i = c])

If the subarray returned by Subtable() is an atom (i.e., a single value with no indexes), you can edit it in a table view, or, if you define an input node for it, directly as an input field.
