Problems view table - source column does not show ...

[sandy081]

Testing #150750

Create an extension that generate diagnostics without source set and you see following:

const diagnosticCollection = vscode.languages.createDiagnosticCollection();
const diagnostics: vscode.Diagnostic[] = [];
 diagnostics.push(new vscode.Diagnostic(new vscode.Range(new vscode.Position(0, 0), new vscode.Position(0, 0)), `test`, vscode.DiagnosticSeverity.Error));
diagnosticsCollection.set(uri, diagnostics);

Also if the source name is longer, it is trimmed off and can't resize the source column to see completely.

I wonder if it is necessary to show source and I think we do not show it in tree mode

Users do want to have the ability to "group" the problems by source so it does make sense to display the source as it allows users to filter the problems based on their source. Having said that, I do agree that we need to make sure that the complete source can be shown.

Pushed changes to:

• increase the maximum width of the "Code" and "Source" columns to have the ability to expand them
• fixed an issue where text overflow ellipsis was not showing correctly on the "Source" column
• there is now a tooltip which should help seeing the complete contents of a column
