How to round table cell by 2 digit?

[xyhuang]

I add
std::cout<<setiosflags(std::ios::fixed)<<setprecision(2);

in table inline std::ostream &operator<<(std::ostream &stream, const Table &table) like this:

inline std::ostream &operator<<(std::ostream &stream, const Table &table) {
  stream << std::setiosflags(std::ios::fixed) << std::setprecision(2);
  const_cast<Table &>(table).print(stream);
  return stream;
}

but it still output a lot of digit

+----------+----------+
|   huang  |    asd   |
+----------+----------+
| 1.111111 | 1.000000 |
+----------+----------+

can you give me some tips?

You don't need to do anything to tabulate to make this happen.

Like I've said before, tabulate simply takes a list of strings. You can format your data however you want before passing it to tabulate.

So this works:

#include "tabulate.hpp"
#include <iomanip>
#include <sstream>

auto to_string(double value, std::size_t precision = 2) {
  std::stringstream stream;
  stream << std::fixed << std::setprecision(2) << value;
  return stream.str();
}

int main() {
  double pi = 3.14159265359;
  double v2 = 0.100000000001;

  tabulate::Table table;
  table.add_row({to_string(pi), to_string(v2)});

  std::cout << table << "\n";
}

will print:

+------+------+
| 3.14 | 0.10 |
+------+------+
