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

|=TOTAL           |    @@=SUM(C)@@ | @@=SUM(C)@@ | @@=SUM(C)@@ |Grand total: @@=SUM(R)@@ |

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

Min, Max and Average

|=Location            |=Morning     |=Noon        |=Evening     |=Average temperature |

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
