Android Code Snippet Print or Save as PDF a Table from B4XTable

Hello everyone, I want to share a method to be able to print or save as pdf a table from B4XTable.

This code is very basic and can be adjusted for any need.

You are free to play with its possibilities.

In this case you will need the following libraries:
-B4XTable 1.21+
-Printing 1.0+ (Link)

Public Sub PrintTable(Table As B4XTable, FileName As String)

    Dim printer As Printer
    printer.Initialize("printer")
    
    Dim PrintString As String = $"
    <!DOCTYPE html>
    <html>
    <head>
    <style>
    Table {
    font-family: arial, sans-serif;
    border-collapse: collapse;
    width: 100%;
    }
    
    td, th {
    border: 1px solid #dddddd;
    text-align: left;
    padding: 8px;
    }
    
    tr:nth-child(even) {
    background-color: #dddddd;
    }
    </style>
    </head>
    <body>
    <h2>File Name: ${FileName}</h2>
    <h4>Date: ${DateUtils.TicksToString(DateTime.Now)}</h4>
    <Table><tr>
    "$
        
    For Each Column As B4XTableColumn In Table.Columns
        PrintString = PrintString & $"<th>${Column.Title}</th>${CRLF}"$
    Next
    PrintString = PrintString & "</tr>"
    
    For i = 1 To Table.Size
        PrintString = PrintString & "<tr>"
        For Each Column As B4XTableColumn In Table.Columns
            Dim Row As Object = Table.GetRow(i).Get(Column.Title)
            PrintString = PrintString & $"<td>${Row}</td>${CRLF}"$
        Next
        PrintString = PrintString & "</tr>"
    Next
    PrintString = PrintString & "</table>"
    
    printer.PrintHtml("job", $"${PrintString}"$)
End Sub

How to Use:

It's very easy, once you create the table and load the data, you can add a button to print the table. It's just assigning the table you want to print the function.

PrintTable(B4XTable, FileName)

- B4XTable = Your table
- FileName = The name you want to show
