TableFeature addColumn does not modify Table

Hi,

I am trying to create a Result Table in the App Builder using this code:

String tableTag = model.result().table().uniquetag("dott");
TableFeature table = model.result().table().create(tableTag, "Table");

Later, when I got the results I try to add them column by column using this method:

table.addColumns(new String[]{"time"}, extraArray);
table.addColumns(new String[]{""+thickness}, realdata);

Both extraArray and realdata are double[][] according to the reference. But when I display the Table in a resultstable view, the Table is empty (also when I try to get the data with e.g getColumnHeaders the added Columns do not show up)

Is there any reason for this. Where did I make a mistake?

Hi Daniel, looks to me like adding a new column only works if there is already some data in the table. Try this code:

String tableTag = model.result().table().uniquetag("dott");
TableFeature table = model.result().table().create(tableTag, "Table");

String header = "title";
double[] data = {1.0, 2.0, 3.0};

table.setTableData(transpose(new double[][]{data}));
table.setColumnHeaders(new String[]{header});

table.addColumns(new String[]{header}, transpose(new double[][]{data}));

Best wishes, Lars
