// Temporary workaround allowing github.com/olekukonko/tablewriter to properly
// format tables with rows containing ANSI terminal links. A PR
// (https://github.com/olekukonko/tablewriter/pull/206) has been opened
// upstream, but we don't know if and when it will be merged. This Go
// compilation directive allows to access the unexported variable and update it
// with what we submitted upstream.
// To be removed once the PR is merged and released.
