The fundamentals of tables in PowerShell
What is a table?
A table in PowerShell is a data structure that allows you to store a collection of values. Each value is accessible via a index, thus facilitating data manipulation. This format is particularly effective for managing large quantities of information.
Create and initialize an array
To create a table, simply: declare a variable and assign several values to it. Here is an example syntax:
$myArray = @(1, 2, 3, 4, 5)
Values are separated by commas and enclosed by parentheses, which allows them to be initialized easily.
Handling array elements
Add and edit values
Manipulating array elements is a key skill. To add a value, use the following method:
$myArray += 6
This will add value 6 to your board. You can also modify a value by specifying its index:
This command replaces the element at index 2 by the value 10.
Delete items
It is also possible to delete an element from an array. Here’s how to do it:
$myBoard = $myBoard | Where-Object {$_ -ne 4}
This order deletes the element with the value 4 of your table.
- Add : Use
+=to add items.
- To modify : Use index to change a value.
- DELETE : The order
Where-Objectis effective.
Curls: a precious help
Using loops
Loops such as For And ForEach are essential for traversing the elements of an array. Here is an example:
foreach ($value in $myArray) { Write-Output $value }
This will display each value contained in the array.

| 📌 Create a board | $myArray = @(value1, value2, value3) |
| ➕ Add a value | $myArray += newValue |
| ✏️ Edit a value | |
| ❌ Delete a value | $myBoard = $myBoard | Where-Object {$_ -nevalueToRemove} |
| 🔄 Browse a table | foreach ($el in $myArray) { … } |
