# Help/Spreadsheet

Phpwiki has extended the Wikicreole syntax of tables so that some simple spreadsheet-like calculations can be performed in tables.

## Syntax

Five functions are available: SUM, AVERAGE, MAX, MIN and COUNT.

They operate on the current row (R) or column (C).

The function is placed in the cell surrounded by @@. Other wiki text can be placed in the cell, but there can be only one formula per cell.

Formula

Meaning

@@=SUM(R)@@

Sum of cells in current row

@@=SUM(C)@@

Sum of cells in current column

@@=AVERAGE(R)@@

Average of cells in current row

@@=AVERAGE(C)@@

Average of cells in current column

@@=MAX(R)@@

Maximum value of cells in current row

@@=MAX(C)@@

Maximum value of cells in current column

@@=MIN(R)@@

Minimum value of cells in current row

@@=MIN(C)@@

Minimum value of cells in current column

@@=COUNT(R)@@

Number of cells in current row (numeric or not, excluding headers and current cell)

@@=COUNT(C)@@

Number of cells in current column (numeric or not, excluding headers and current cell)

## Examples

### Sum

```|=Region          |=Telecom Sales  |=Power Sales |=Other       |=TOTAL      |
|=Europe          |            320 |          80 |         120 |@@=SUM(R)@@ |
|=Asia            |            580 |         723 |         564 |@@=SUM(R)@@ |
|=North America   |            235 |          60 |         109 |@@=SUM(R)@@ |
|=South America   |            120 |          35 |          82 |@@=SUM(R)@@ |
|=Antarctica      |              0 |           0 |          12 |@@=SUM(R)@@ |
|=TOTAL           |    @@=SUM(C)@@ | @@=SUM(C)@@ | @@=SUM(C)@@ |Grand total: @@=SUM(R)@@ |```
Region Telecom Sales Power Sales Other TOTAL
Europe 320 80 120 520
Asia 580 723 564 1867
North America 235 60 109 404
South America 120 35 82 237
Antarctica 0 0 12 12
TOTAL 1255 898 887 Grand total: 3040

Total of both colums and rows is calculated automatically by wiki.

### Count and Sum

```|=Bug                |=Priority   |=Subject             |=Status     |=Days to fix
| 1231               | Low        | File Open ...       | Open       | 3
| 1232               | High       | Memory Window ...   | Fixed      | 2
| 1233               | Medium     | Usability issue ... | Assigned   | 5
| 1234               | High       | No arrange ...      | Fixed      | 1
| Number of bugs: @@=COUNT(C)@@ | |                     |            | Total: @@=SUM(C)@@ days```
Bug Priority Subject Status Days to fix
1231 Low File Open ... Open 3
1232 High Memory Window ... Fixed 2
1233 Medium Usability issue ... Assigned 5
1234 High No arrange ... Fixed 1
Number of bugs: 4 Total: 11 days

### Min, Max and Average

```|=Location            |=Morning     |=Noon        |=Evening     |=Average temperature |
| Paris               | 7           | 13          | 10          | @@=AVERAGE(R)@@     |
| London              | 3           | 10          | 8           | @@=AVERAGE(R)@@     |
| Berlin              | 9           | 15          | 12          | @@=AVERAGE(R)@@     |
| Tokyo               | 12          | 20          | 16          | @@=AVERAGE(R)@@     |
| Maximum temperature | @@=MAX(C)@@ | @@=MAX(C)@@ | @@=MAX(C)@@ |                     |
| Minimum temperature | @@=MIN(C)@@ | @@=MIN(C)@@ | @@=MIN(C)@@ |                     |```
Location Morning Noon Evening Average temperature
Paris 7 13 10 10
London 3 10 8 7
Berlin 9 15 12 12
Tokyo 12 20 16 16
Maximum temperature 12 20 16
Minimum temperature 3 10 8

## Limitations

The formulas are evaluated line per line, from left to right.

So this will work:

```|          10 |         -13 | @@=SUM(R)@@ |
|          15 |          17 | @@=SUM(R)@@ |
| @@=SUM(C)@@ | @@=SUM(C)@@ | @@=SUM(R)@@ |```
 10 -13 -3 15 17 32 25 4 29

And this will not:

```| @@=SUM(R)@@ |          10 |         -13 |
| @@=SUM(R)@@ |          15 |          17 |
| @@=SUM(R)@@ | @@=SUM(C)@@ | @@=SUM(C)@@ |```
 -3 10 -13 32 15 17 0 25 4
