Solution 2

In will compile if you write

C#

table.SetWidths(new int[] { tblwidth, });

But it's likely that you don't understand what you are doing yourself. The array should represent not one width, but a set of width of the columns. Do you think you need a table with just one column? Why?

Please see: http://itextpdf.com/examples/iia.php?id=76[^].

I am actually a bit confused about this line (found in the link you have provided)

table.setWidths(new float[]{2, 1, 1});

The method actually needs a float array, but the compiler asks for an integer one... How is it possible?

Sergey Alexandrovich Kryukov 28-Sep-14 17:39pm

If a compiler says it should be integer array, it should by such array. Look at the method signature.

Actually, there are two overloads of that method... I do not understand why the compiler asks for an integer array.

void setWidths(float[] relativeWidths)
Sets the relative widths of the table.
void setWidths(int[] relativeWidths)
Sets the relative widths of the table.

Source: http://api.itextpdf.com/itext/com/itextpdf/text/pdf/PdfPTable.html#setWidths(float[])

And in the code I would have added the cells inside the for loop and, since you need to set the widths once, I would have put the array declaration and the table.setwidths outside the loop...

Maybe tblwidth is integer. But you can use any of the suitable methods, depending on what you want.

Hi,

TBLWidth is a float array. Change

float[] tblwidth = new float[3];

to

int[] tblwidth = new int[3];

and use integers (maybe with explicit conversions (int)) in the array!

The error occurs because the method accepts as parameter an integer array, not a float one.
If you have problems with float-int conversion put the operator (int) before any float value

I.E.
float f= whateveryouwant
int i = (int)f

You can use Math.Round if you need rounding the float value and not truncating it.

PS: useful piece of advice for next questions: try to be more specific in writing the title, otherwise less people will watch them. :-)
