TablePress supports mathematical functions and formulas in table cells, in a very similar way as they can be used in Excel or other spreadsheet applications. Almost all Excel formulas are supported — just make sure to use their English name!
The following table shows some examples of made-up data and formulas that calculate something:
| A | B | C | D | |
|---|---|---|---|---|
| 1 | Data 1: | Data 2: | Formulas: | Result: |
| 2 | 1 | 0.4 | =A2+A3+A4 | 8 |
| 3 | 2 | -0.9 | =Sum: {SUM(B2:B8)} | Sum: 11.5 |
| 4 | 5 | 4.5 | =SIN(PI()/2) | 1 |
| 5 | 4 | -0.1 | =ABS(B3)+CEIL(B4,0) | 0.9 |
| 6 | 3 | 2.2 | =POWER(A4,A5) | 625 |
| 7 | 7 | -0.4 | =MEDIAN(A2:A8) | 4 |
| 8 | 8 | 5.8 | =IF(A4>A5,1,0) | 1 |
The content of a cell is evaluated as a formula, if it starts with the equal sign =.
Formulas can reference other cells, by stating the column letter and the row number. It is possible to use single references, like A2, or to reference multiple cells in a row, column, or even block, by using the colon (:) operator. With that, A2:A8 means all cells in the A column, while A3:E3 would refer to all cells in the third row.
Those references will even be adjusted automatically whenever the referenced cell changes position in the table, e.g. because its row or column is moved or because another row or column is deleted or inserted.
Also, it is possible to wrap a formula in text, with the syntax =TEXT{FORMULA}TEXT. The cell content still has to start with the equal sign = and the formulas then have to be wrapped in curly brackets {and }. This can be seen in the example =Sum: {SUM(B2:B8)} in cell C3 in the table above.
Most of the supported functions expect only one argument, either a number, or a reference to a cell, while some of the functions will work with multiple arguments, either given as a comma-separated list, or by using the colon operator that is described above.
These functions are supported by TablePress:

> | greater than |
Placeholder variables:
TABLE_ID | ID of the current table |
NUM_ROWS | Number of rows of the current table |
NUM_COLUMNS | Number of columns of the current table |

Other functions:
number_format(x,d) | Formats x with d decimals after the period . where the comma , will be used as the thousands delimiter (if x has more than four digits) |
number_format_eu(x,d) | Formats x with d decimals after the comma , where the period . will be used as the thousands delimiter (if x has more than four digits) |
sum(…) | Sum of the arguments |
product(…) | Product of the arguments |
rand_int(a,b) | Random integer between a and b |
rand_float() | Random real number between 0 and 1 |

counta(…) | Number of non-empty values from the arguments |
Trigonometric functions:
sin(x) | Sine of x |
sinh(x) | Hyperbolic sine of x |
arcsin(x)(also as asin(x)) | Inverse sine of x |
arcsinh(x)(also as asinh(x)) | Inverse hyperbolic sine of x |

Note that all of them work with pure numbers only. If you need to do calculations on e.g. dates or work with text, you should consider using Excel or similar and export the final results table as a CSV file and import that into TablePress.
