When adding tables in RadPdfProcessing using the [RadFixedDocumentEditor](https://docs.telerik.com/devtools/document-processing/libraries/radpdfprocessing/editing/radfixeddocumenteditor), tables may sometimes split across pages if they cannot fit within the remaining space on the current page. To ensure a table fits entirely on one page and starts on a new page if necessary, you can adopt a strategy to measure the table size and calculate the remaining page height.

### Using RadFixedDocumentEditor

Measuring the table and calculating the remaining page height is a valid approach. Here's how you can implement it:
32-
33-
```csharp
34-
var tableSize = table1.Measure().Height;
35-
double remainingPageHeight = availablePageHeight - tableSize;
36-
37-
if (remainingPageHeight <= minimumRemainingHeight)
38-
{
39-
editor.InsertPageBreak();
40-
editor.InsertTable(table1);
41-
editor.InsertLineBreak();
42-
availablePageHeight = editor.SectionProperties.PageSize.Height
43-
- (editor.SectionProperties.PageMargins.Top + editor.SectionProperties.PageMargins.Bottom)
44-
- tableSize - lineBreakSize;
45-
}
46-
else
47-
{
48-
editor.InsertTable(table1);
49-
editor.InsertLineBreak();
50-
}
51-
```

### Using FixedContentEditor for Precise Control

For more precise positioning, you can use the [FixedContentEditor](https://docs.telerik.com/devtools/document-processing/libraries/radpdfprocessing/editing/fixedcontenteditor). This editor allows you to measure and draw tables with exact positioning. Below is an example implementation:

### Key Points
110-
1. **RadFixedDocumentEditor** is flow-based, and requires measuring and adding page breaks manually.
111-
2. **FixedContentEditor** provides precise control over positioning and avoids table splits by managing the drawing location explicitly.
