Original GitHub issue: https://github.com/rivo/tview/issues/1093

I am trying to use this library which seems to be easy to use and understand. However, I'm having two problems and I didn't find anything in the documentation which could help.

This is the sample code I'm using. It creates a two column grid which contains a table on the left column.

One problem is, that I'd like the table to fill the whole column, something like width: 100% in CSS. The other problem is that it seems to be impossible to add cell spacing. I didn't find a solution for both.

I'd appreciate any help with thes issues!

Many thanks in advance,
Tom

Hi, have you tried this?
func (data *Data) GetCell(row, column int) *tview.TableCell { return tview.NewTableCell(data.Rows[row][column]).SetExpansion(1) }

Sorry for the late reply. Yes, SetExpansion(1) did the trick.

But I've got another problem: I want the table to have a header. So my idea was to put the header captions as row[0] and set the first row as non-selectable. However, it seems to be impossible to do that. The only thing I came up with was this:

table.SetContent(data).SetFixed(0, 0)
for column, _ := range rows[0] {
	table.GetCell(0, column).SetSelectable(false)
}

But it doesn't work, the first row is still selectable.

Edited to add:

I managed to fix this, I replaced table.SetContent(data).SetFixed(0, 0) with:

	var headers = []string{
		"Vorname",
		"Nachname",
		"Geburtsjahr",
	}

	for column, header := range headers {
		table.SetCell(0, column, tview.NewTableCell(header).SetSelectable(false))
	}

	for row, entry := range rows {
		for column, cell := range entry {
			table.SetCell(row+1, column, tview.NewTableCell(cell))
		}
	}

Now I have a non-selectable table header. However, now the table is not expanded anymore:

Here's the gist of the changed example
