ASPOSE.WORDS. Dynamic creation of Tables

Aspose.Words Product Family
#1

I’d like to create dinamically many tables.

Could you please provide me with sample how to do that?

I tried to do that in following manner but failed and no example found on this site.

builder.Writeln();
// Adding header row of Summary Table
DataRow drHeader = tblSummary.Rows[0];
builder.Font.ClearFormatting();
builder.StartTable();
for (int j = 0; j < tblSummary.Columns.Count; j++)
{
    builder.RowFormat.Alignment = RowAlignment.Center;
    builder.InsertCell();
    builder.Write(drHeader[j].ToString());
}
builder.EndRow();
builder.EndTable();

// --... After that I'm adding new table like that:
builder.Font.ClearFormatting();
builder.StartTable();
for (int i = 0; i < tbl.Rows.Count; i++)
{
    for (int j = 0; j < tbl.Columns.Count; j++)
    {
        builder.RowFormat.Alignment = RowAlignment.Center;
        builder.InsertCell();
        builder.Write(tbl.Rows[i][j].ToString());
    }
    builder.EndRow();
}
builder.EndTable();

But that code doesn’t produce tables in Aspose.Word document.

Only 1 table can be buit successfully (without another one).

Hi Alex,

Refer to this thread here for tips on how to get started dynamically building a simple table in your document. Try that code and see if it generates a table in your document.

Also check that tblSummary.Columns.Count is returning a value > 0. This could be the cause of no cells appearing in the document.

Please feel free to ask if you have any problems.

Thanks,

Hi Adam!
The problem not in that I cannot build the table dynamically - but in that I cannot build 2 (and more) tables dynamically one after another.
Like that:
(these table just for example)

Table 1
-----------------------------
| UserID | OrderID |
------------------------------
125 | 546879865436|
687 | 654683516546|
------------------------------|
Table 2
----------------------------------|
| UserName | Birthday Date |
----------------------------------|
Alex | 1980 |
Michael | 1979 |
----------------------------------|

The problem may be caused by:

builder.StartTable();
builder.EndRow();
builder.EndTable();

I’m not sure that I use them correctly.

I can build table and add rows, but how to do that for many tables and add them into 1 word doc. ?

Please, provide me with example.
The last one you pointed didn’t help me.

Hi Alex,

Please try the following code. It creates 2 tables in one document.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.Writeln(@"Table1");
// Create first table
builder.InsertCell();
builder.Write(@"UserID");
builder.InsertCell();
builder.Write(@"OrderID");
builder.EndRow();
builder.InsertCell();
builder.Write(@"125");
builder.InsertCell();
builder.Write(@"546879865436");
builder.EndRow();
builder.InsertCell();
builder.Write(@"687");
builder.InsertCell();
builder.Write(@"654683516546");
builder.EndRow();
builder.EndTable();
builder.Writeln();
builder.Writeln(@"Table2");
// Create second table
builder.InsertCell();
builder.Write(@"UserName");
builder.InsertCell();
builder.Write(@"Birthday Date");
builder.EndRow();
builder.InsertCell();
builder.Write(@"Alex");
builder.InsertCell();
builder.Write(@"1980");
builder.EndRow();
builder.InsertCell();
builder.Write(@"Michael");
builder.InsertCell();
builder.Write(@"1979");
builder.EndRow();
builder.EndTable();
doc.Save(@"2tables.docx");

Thank you for that example.

But my document logic is more coplex, that’s why I have a problems here.
Below two methods which add tables and chart into word.doc.
Could you please have a glance to check what is wrong there:

// This method is triggered in the loop - adding many tables in such a way

public static void AddTableToDocument(DataTable tbl, DataTable tblSummary, int iQuestionNum, ref DocumentBuilder builder, Stream chartStream, string sQuestionText)
{
    Section currentSection = builder.CurrentSection;
    PageSetup pageSetup = currentSection.PageSetup;
    pageSetup.TopMargin = 1;

    builder.InsertBreak(BreakType.PageBreak);

    // Adding Question Text
    string sCompleteQuestionText = "Question No. " + iQuestionNum.ToString() + ": ";
    sCompleteQuestionText += sQuestionText;
    builder.Font.Bold = true;
    builder.Font.Size = 10;
    builder.Writeln(sCompleteQuestionText);
    // Adding Question Text. End

    //AddSummaryTable(ref tblSummary, ref iQuestionNum, ref builder);

    // Adding Distribution Table
    builder.Font.ClearFormatting();
    // builder.StartTable();

    for (int i = 0; i < tbl.Rows.Count; i++)
    {
        for (int j = 0; j < tbl.Columns.Count; j++)
        {
            builder.RowFormat.Alignment = RowAlignment.Center;
            builder.InsertCell();
            builder.Write(tbl.Rows[i][j].ToString());

        }
        builder.EndRow();
    }

    builder.EndTable();

    if (chartStream != null)
    {
        builder.Writeln();

        if (chartStream.Length != 10802)
        {
            builder.InsertImage(chartStream);
        }
        else
        {
            // TODO: CHANGE ABLOSUTE PATHS IN WHOLE SOLUTION

        }
    }
    builder.MoveToDocumentEnd();
}

// Adding onothe one table

private static void AddSummaryTable(ref DataTable tblSummary, ref int iQuestionNum, ref DocumentBuilder builder)
{
    builder.Writeln();
    // Adding header row of Summary Table
    DataRow drHeader = tblSummary.Rows[0];
    builder.Font.ClearFormatting();

    for (int j = 0; j < tblSummary.Columns.Count; j++)
    {
        builder.RowFormat.Alignment = RowAlignment.Center;
        builder.InsertCell();
        builder.Write(drHeader[j].ToString());
    }

    builder.EndRow();
    builder.EndTable();
    // builder.Writeln();

    // Adding header row of Summary Table. End

    //string selectExpression = "QNumber = " + "’" + iQuestionNum.ToString() + "’";
    //DataRow[] aRow = tblSummary.Select(selectExpression);

    //if (aRow.Length > 0)
    //{
    // builder.Font.ClearFormatting();
    // builder.StartTable();

    // for (int j = 0; j < tblSummary.Columns.Count; j++)
    // {
    // builder.RowFormat.Alignment = RowAlignment.Center;
    // builder.InsertCell();
    // builder.Write(aRow[0][j].ToString());
    // }

    // builder.EndRow();
    // builder.EndTable();
    //}

Hi Alex,

I’d like to clarify one thing. Are the tables that you create after the first table missing in the document completely or they just merged with the first table?

Thanks,

#8

Tables are created and not merged with other tables.
I don’t use functionality in the meaning Aspose “merge”.

Please look at attached picture.
I need to put in Summary Table in word.doc - method AddSummaryTable
Method AddTableToDocument does its job right**.**
But when** I call method AddSummaryTable within AddTableToDocument then problems start - word doc loose its structure and tables are not shown correctly.

#9

Hi.

Could you attach a document where I can see incorrect tables?

Thanks,

#10

Word.doc is attached

#11

Hi,

Please see attached sample code. I took the code you posted before and made a modification to use string array instead of DataTable. The last page of the attached output.doc contains 2 tables added by my sample code. I don’t see any issues with that.

Probably you use some old version of Aspose.Words.NET so please try the latest version which is 9.0.0 (https://downloads.aspose.com/words/net).

Regards,

#12

I located where problem is -
in another two methods: BeginningDocument and BuildCoverPage
Could you please point out me exact place in those methods which causes the problem?

I attached Class which contains all methods (including above mentioned) for building word doc.
Thanks!

P.S. I use Aspose.Words for .NET 9.0.0

#13

Hi,

I can’t run the code you attached because it uses external data and images. Could you create a simple test application that would help me to reproduce the issue on my side? Please attach the test application and the output document that this application generates.

Thanks,
