TWiki Spreadsheet Plugin
This Plugin adds speadsheet capabilities to DENX topics. Formulae like%CALC{"$INT(7/3)"}%
are evaluated at page view time. They can be placed in table cells and outside of tables. In other words, this Plugin provides general formula evaluation capability, not just classic spreadsheet functions.
Example:
| Interactive example: | |||||||||||||||
The formula next to "Total" is %CALC{"$SUM( $ABOVE() )"}% . (you see the formula instead of the sum in case the Plugin is not installed or not enabled.) |

Syntax Rules
The action of this Plugin is triggered by the%CALC{"..."}%
variable, which gets rendered according to the built-in function(s) found between the quotes.
- Built-in function are of format
$FUNCNAME(parameter)
- Functions may be nested, e.g.
%CALC{"$SUM( R2:C$COLUMN(0)..R$ROW(-1):C$COLUMN(0) )"}%
- Functions are evaluated from left to right, and from inside to outside if nested
- The function parameter can be text; a mathematical formula; a cell address; or a range of cell addresses
- Multiple parameters form a list; they are separated by a comma, followed by optional space, e.g.
%CALC{"$SUM( 3, 5, 7 )"}%
- A table cell can be addressed as
R1:C1
. Table address matrix:R1:C1
R1:C2
R1:C3
R1:C4
R2:C1
R2:C2
R2:C3
R2:C4
- A table cell range is defined by two cell addresses separated by
".."
, e.g. "row 1 through 20, column 3" is:R1:C3..R20:C3
- Lists can refer to values and/or table cell ranges, e.g.
%CALC{"$SUM( 3, 5, $T(R1:C7), R1:C11..R1:C15 )"}%
- Formulae can only reference cells in the current or preceeding row of the current table; they may not reference cells below the current table row
- Formulae can also be placed outside of tables; they can reference cells in the preceeding table
