How to Adjust First Column to Fill Remaining Space in .Net Core Word?

Syncfusion; Essential; DocIO is a .NET Word library used to create, read, edit, and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can adjust the first column to fill the remaining space in a Word table using C#.

Steps to adjust the first column to fill the remaining space in a Word table:

1. Create a new .NET Core console application project.
   
   
2. Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your project from NuGet.org.
   
   

3. Include the following namespaces in the Program.cs file.
   C#

using Syncfusion.DocIO.DLS;
using Syncfusion.DocIO; 

4. Use the following code example to adjust the first column to fill the remaining space in a Word table.
   C#

// Load the input Word document from file stream
using (FileStream docStream = new FileStream(Path.GetFullPath(@"Data/Input.docx"), FileMode.Open, FileAccess.Read))
{
   // Open the Word document
   using (WordDocument document = new WordDocument(docStream, FormatType.Docx))
   {
       // Find all tables in the document
       List<Entity> tables = document.FindAllItemsByProperty(EntityType.Table, null, null);
       // Initialize variables
       bool isFirstCell = false; // Flag to identify the first cell in each row
       WTableCell firstCellReference = new WTableCell(document); // To store the reference to the first cell
       float totalCellWidth = 0; // Accumulate width of cells except the first one
       // Loop through each table found in the document
       foreach (WTable table in tables)
       {
           // Iterate through each row in the table
           foreach (WTableRow row in table.Rows)
           {
               // Reset variables for each row
               totalCellWidth = 0;
               isFirstCell = false;
               // Iterate through each cell in the row
               foreach (WTableCell cell in row.Cells)
               {
                   if (!isFirstCell)
                   {
                       // Identify the first cell in the row
                       isFirstCell = true;
                       firstCellReference = cell; // Store the first cell reference
                   }
                   else
                   {
                       // Add the width of remaining cells in the row
                       totalCellWidth += cell.Width;
                   }
               }
               // Calculate the remaining width by subtracting totalCellWidth from page width
               float pageWidth = (table.Owner.Owner as WSection).PageSetup.ClientWidth;
               float remainingWidth = pageWidth - totalCellWidth;
               // Set the width of the first cell to the remaining width
               firstCellReference.Width = remainingWidth;
           }
       }
       // Save the modified document to a new file
       using (FileStream docStream1 = new FileStream(Path.GetFullPath(@"Output/Result.docx"), FileMode.Create, FileAccess.Write))
       {
           document.Save(docStream1, FormatType.Docx);
       }
   }
}
