# Data tables
The MDataTable component is used for displaying tabular data. Features include sorting, searching, pagination, content-editing, and row selection.
The standard data-table will by default render your data as simple rows.
You can override the default filtering used with Search prop by supplying a function to the CustomFilter prop. If you
need to customize the filtering of a specific column, you can supply a function to the Filter property on header items.
The signature is
Func<object, string, TItem, bool>. This function will always be run even if
Search prop has not been provided. Thus you need to make sure to exit early with a value of true if filter should not be
Using the Dense prop you are able to give your data tables an alternate style.
You can easily disable specific columns from being included when searching through table rows by setting the property ** Filterable** to false on the header item(s). In the example below the dessert name column is no longer searchable.
MDataTable renders a default footer using the
MDataFooter component. You can pass props to this component using
Using the GroupBy and GroupDesc props you can group rows on an item property. The ShowGroupBy prop will show a group button in the default header. You can use the Groupable property on header items to disable the group button.
# Hide default header and footer
You can apply the HideDefaultHeader and HideDefaultFooter props to remove the default header and footer respectively.
You can use the Loading prop to indicate that data in the table is currently loading. If there is no data in the table, a loading message will also be displayed. This message can be customized using the LoadingText prop or the LoadingContent slot.
# Multi sort
Using the MultiSort prop will enable you to sort on multiple columns at the same time. When enabled, you can pass arrays to both SortBy and SortDesc to programmatically control the sorting, instead of single values.
The ShowSelect prop will render a checkbox in the default header to toggle all rows, and a checkbox for each default row. You can also switch between allowing multiple selected rows at the same time or just one with the SingleSelect prop.
The data table exposes a Search prop that allows you to filter your data.

MSimplleChecbox component is used internally and will respect
# CRUD Actions
MDataTable with CRUD actions using a
MDialog component for editing each row.
MEditDialog component can be used for editing data directly within a
MEditDialog. You can block the closing of
MEditDialog when clicked outside by adding the Persistent prop.
ShowExpand prop will render an expand icon on each default row. You can customize this with the
ItemDataTableExpandContent slot. The position of this slot can be customized by adding a column
Value="data-table-expand" to the Headers array. You can also switch between allowing multiple expanded rows
at the same time or just one with the
SingleExpand prop. Row items require a unique key property for expansion to
work, use ItemKey prop to specify.
# External pagination
Pagination can be controlled externally by using the individual props, or by using the Options prop.
# External sorting
Sorting can also be controlled externally by using the individual props, or by using the the Options prop.
# Server-side paginate and sort
If you’re loading data already paginated and sorted from a backend, you can use the ServerItemsLength prop. Defining this prop will disable the built-in sorting and pagination, and you will instead need to use the available events ( OnPageUpdate, OnSortByUpdate, OnOptionsUpdate, etc) to know when to request new pages from your backend. Use the Loading prop to display a progress bar while fetching data.
