# Tabeller

Vis data i PowerShell Universal-portalwidgets ved hjælp af Table-komponenten, herunder brugerdefineret kolonneindhold og kolonner med handlingsknapper.

Tabeller kan bruges til at vise data til brugere i et gitterformat.

## Grundlæggende tabel

Tabeller består af en datakilde og en række kolonner. De kan bruge PowerShell-variabler som en datakilde. Et simpelt script kan indlæse alle tjenesterne på maskinen i en variabel.

```powershell
$Variables["Services"] = Get-Service
```

Tabellen ville derefter vise et bestemt antal egenskaber som kolonner.

```markup
<Table DataSource="$Services">
    <PropertyColumn Property="Name"></PropertyColumn>
    <PropertyColumn Property="Status"></PropertyColumn>
</Table>
```

## Kolonneindhold

Egenskabskolonner kan levere brugerdefineret indhold baseret på den række, der gengives. Brug variablen `$Context` til at referere til den aktuelle række.

```markup
<Table DataSource="$Services">
    <PropertyColumn Property="Name"></PropertyColumn>
    <PropertyColumn Property="Status">
        <Alert Message="$context.Status" />
    </PropertyColumn>
</Table>
```

## Handlingskolonner

Actions-kolonner er ikke knyttet til en bestemt egenskab og bruges til visningshandlinger som f.eks. knapper.

```markup
<Table DataSource="$Services">
    <PropertyColumn Property="Name"></PropertyColumn>
    <PropertyColumn Property="Status">
        <Alert Message="$context.Status" />
    </PropertyColumn>
    <ActionColumn>
        <Button OnClick="ShowStatus">Show Status</Button>
    </ActionColumn>
</Table>
```

For at referere til den aktuelle række i knapklikket skal De bruge parameteren `$Context`.

```powershell
function ShowStatus {
    param($Context)
    $Message.Success($Context.Status.ToString())
}
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.devolutions.net/powershell-universal/da/portal/portal-widgets/tables.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
