Properties
Readonly length
The TTable.length property returns the number of elements in an array.
The value of this property is an 32-bit unsigned integer that is always greater than the greatest index in the array.
Readonly result
String with the calculated result in the table.
In this string, the calculation of the total, the average, or the number of elements can be set.
Methods
concat
-
The method returns a new array that includes the array of table elements concatenated with other arrays and/or values passed as arguments.
Important: the returned value is a regular array, not a table.
Parameters
-
Rest ...items: (T | ConcatArray<T>)[]
Returns T[]
A new array containing all the elements.
-
delete
-
The method deletes a specific row from a table.
Parameters
-
index: number
Returns void
-
every
-
The method tests whether at least one element in the array passes the test implemented by the callback function.
Important: the method returns
truewhen applied to an empty table, no matter the conditions.Parameters
-
predicate: function
-
Parameters
-
value: T
-
index: number
-
array: readonly T[]
Returns unknown
-
-
-
Optional thisArg: any
Returns boolean
Returns
trueif the checking function returnstruefor each element of the table. Otherwise, returnsfalse. -
filter
-
The method creates a new array consisting of all the elements that meet the conditions set in the callback function.
Important: the returned value is a regular array, not a table.
Parameters
-
predicate: function

Parameters
-
value: T
-
index: number
-
array: readonly T[]
Returns unknown
-
-
-
Optional thisArg: any
Returns T[]
A new array with elements that met the conditions. If no elements meet the conditions, an empty array will be returned.
-
find
-
The method returns the value of the item in the table that is the first one to meet the conditions passed in the
predicatefunction. Otherwise, it returnsundefined.Parameters
-
predicate: function

Table
Table is a type of variable that stores an array of data (table rows).
Each row is a separate element of an array. It is an object whose properties are defined by the table’s columns. Read more about working with tables in Getting started with the Table data type.
