WPF: How To append text in Richtextbox in column/ tab separed.

Question

Hello,

In my WPF application I would like to use a Richtextbox for appearing data in column style ( like tab separated but not a real table element).

I search a lot, but I did not find the way how to append text continuously: new string data tab separated from last text on the Richtextbox. And the distance between first and second 'column' is equal.

Here is a example that I found, this almost that I want, just I would like it in WPF version.

Can you help me and provide a little example how I need to do this?
Yes, I not added code part because I don't know how to do it. So, there is no part of code which not work; simple: I don't have :(

Thanks for the help.

Viorel-1's answer is great. If it's just a simple string arrangement, you could set the distance between strings by adding \t as required.
xaml:

 <RichTextBox Name="rtb" Width="400" Height="300" HorizontalAlignment="Left"/>  

xaml.cs:

string txt ="Breakfast\tLunch\t\tDinner\n" +  
       "Coffee\t\tSoda\t\tWine\n" +  
       "Bagel\t\tSandwich\tSalad\n" +  
       "Fruit\t\tChips\t\tTofuburger\n" +  
            "\t\tCookie\t\tVeggies";  

      rtb.AppendText(txt);  

The result:

Try adding a <Table> element to your textbox:

<RichTextBox>
    <FlowDocument>
        <Table>
            <Table.Columns>
                <TableColumn />
                <TableColumn />
                <TableColumn />
            </Table.Columns>
            <TableRowGroup x:Name="myRows"/>
        </Table>
    </FlowDocument>
</RichTextBox>

To insert a new row programmatically:

var r = new TableRow();

r.Cells.Add( new TableCell( new Paragraph( new Run( "Breakfast" ) ) ) );
r.Cells.Add( new TableCell( new Paragraph( new Run( "Lunch" ) ) ) );
r.Cells.Add( new TableCell( new Paragraph( new Run( "Dinner" ) ) ) );

myRows.Rows.Add( r );

Use <TableColumn Width="..."/> to set the width of the columns.
