AutoFit

[kaimon]

I am creating a table and trying to add it to a spire document.

However, when I try to set the layout to autofit to contents, I get an "Object reference is null error" that comes from within spire.doc assemblies.
No further information is given.

The code I'm using is below:


private Table createTable(string tableJson, Document document)
{

JArray jsonTable = (JArray)JsonConvert.DeserializeObject(tableJson);
JArray rowtable = (JArray)jsonTable[0];
int rowCount = jsonTable.Count();
int cellCount = rowtable.Count();

Table table = new Table(document, true, 1f);
table.ResetCells(rowCount, cellCount);

populateCells(table, jsonTable);

table.AutoFit(AutoFitBehaviorType.AutoFitToContents);
return table;

}

Hi,

Thanks for your inquiry.
After testing your case with the latest Spire.Doc Pack(hot fix) Version:7.11.1, I didn't reproduce your issue. Below is my full code:

Code: Select all

            Document doc = new Document();
            Section section = doc.AddSection();
            Table table = section.AddTable(true);
            table.ResetCells(3, 5);
            for (int i = 0; i < table.Rows.Count; i++)
            {
                TableRow row = table.Rows[i];
                for (int j = 0; j < row.Cells.Count; j++)
                {
                    TableCell cell = row.Cells[j];
                    cell.AddParagraph().AppendText("Row" + i.ToString() + "cell" + j.ToString());
                }
            }

            table.AutoFit(AutoFitBehaviorType.AutoFitToContents);
            doc.SaveToFile("19500.docx",FileFormat.Docx);

I firstly suggest you try to use the latest version. If the issue still exists, please provide full code or a sample project for showing your issue.

HI,

Sorry the 7.11.1 hotfix didn't work.

I'm getting the same "object reference not set error".

When I look at the exception stack, its being raised from within your Table class

at Spire.Doc.Table.ᜉ()
at Spire.Doc.Table.ᜊ()
at Spire.Doc.Table.ᜀ(AutoFitBehaviorType A_0)
at Spire.Doc.Table.ᜏ()
at Spire.Doc.Table.AutoFit(AutoFitBehaviorType behavior)

Is there a mode I can set to get the returned exception to be more detailed?

I've further debugged this and it seems the autofit call will fail if the table hasn't been created using a Section.AddTable method.

In my original code, I created the table directioned by instantiating a new Table().

However, even though i no longer get the object reference not set error, it looks like the table i'm trying to AutoFit to contents doesn't display correctly even after making the call.

Happy to send you my sample doc files if you can give me an email address..

I've managed to get this working.

It seems like it was an issue with my word docs styling.
