Simple table processor on java and swing.

Сapabilities:

- Calculation of expressions
- Customization table borders/background
- Spanning cells and ranges:
    - up
    - down
    - left
    - right
- Moving cells and ranges
- Import/export tables

Expressions:

First symbol should be '='. Exists ability to refer on cell like a "A1". if expression contains cell reference, reference should changes on cell moving. For example, expression "=A1" after moving right on one column is "=B1". You can fix column on row with '$' symbol. For example, "=$A$1".

Functions, that can exists in expression:

- sin
- cos
- abs

Aggregate functions:

- min
- max
- mean
- sum

Argument of aggregate function is cell range: :. First reference must have less or equal row and less or equal column.

Expression can contains +, -, /, * and power(^) binary operations, +, - unary operations. Case is not important.

Example of expression:

=($A$1*B2^3*(sum(a1:a10)-1)/4+(-1)*mean(a1:a10)*min(a1:a2)/6)^B1

After spanning on one row down:

=($A$1*B3^3*(sum(a2:a11)-1)/4+(-1)*mean(a2:a11)*min(a2:a3)/6)^B2

Customization of table can be done with right settings panel on tab.
