More than 15 columns in Novacode DocX Table

Question

Is there a way to create a word table with more than 15 columns using Novacode DocX?

If I create a new table with greater than 14 columns, the table doesn't appear. I can get around this by doing something like this:

int addCols = Math.Min(data.colCount, 14);
Table docTable = doc.InsertTable(data.rowCount, addCols);

And then later this:

docTable.InsertColumn();

However, if I try to do this more than once to create a table with 16 or more columns, I have the same issue where the table doesn't appear.

Is there any way around this?

Here is my way around this. This might not work if you need many different tables with random large numbers of columns because it would take a lot of work.

using (DocX template = DocX.Load("template.docx"))
{
     Novacode.Table tempTable;
     using (DocX template2 = DocX.Load("template2.docx"))
     {
          tempTable = template2.Tables[0];
     }
     Novacode.Table t1 = doc.InsertTable(tempTable);
     t1.InsertRow();
     t1.InsertRow();
     template.Save();
}

This is a possible solution. template is the DocX you are inserting a Table into. template2 contains pre-made Tables that are 1 row and have as many columns as you would like. So template2.Table[0] would be a Table size (1,15). You can then add more Tables to template2 (outside of code by creating them within the document in Microsoft Word) growing larger: template2.Table[1] would be a Table size (1,16). The only issue is if you have a lot of different number of column Tables that you need to work with. Novacode-dox is not a very good library for building things from scratch.

Hope this might be a work around for you.

There is something like a bug in the library. When you create a table with many columns it becomes unusable. Reason is, that each column is created with its initial width. When you create table (independatly of the used method: InsertTable, AddTable, InsertTableBeforeSelf etc.) with many columns and the sum of their widths exceeds the document width - the table becomes unusable.

I solved this problem by adding columns in cycle and decreasing their width. My code is similar to this:

private void CreateSampleTable(DocX document)
{
    int rowsCount = 10;
    int columnsCount = 20;
    int columnWidth = 30;

    Table sampleTable = document.AddTable(rowsCount, 1);
    foreach (Row row in sampleTable.Rows)
    {
        row.Cells[0].Width = columnWidth;
    }

    for (int colIndex = 1; colIndex < columnsCount; colIndex++)
    {
        sampleTable.InsertColumn(colIndex);
        foreach (Row row in sampleTable.Rows)
        {
            row.Cells[colIndex].Width = columnWidth;
        }
    }

    Paragraph par = document.InsertParagraph();
    par.InsertTableBeforeSelf(sampleTable);
}
