+// A cell represents a segment of text terminated by tabs or line breaks.

+// ('\t') terminated cell.

+
+// A Writer is a filter that inserts padding around tab-delimited
+// columns in its input to align them in the output.
+//
+// The Writer treats incoming bytes as UTF-8 encoded text consisting
+// of cells terminated by (horizontal or vertical) tabs or line
+// breaks (newline or formfeed characters). Cells in adjacent lines
+// constitute a column. The Writer inserts padding as needed to
+// make all cells in a column have the same width, effectively
+// aligning the columns. It assumes that all characters have the
+// same width except for tabs for which a tabwidth must be specified.
+// Note that cells are tab-terminated, not tab-separated: trailing
+// non-tab text at the end of a line does not form a column cell.
+//
+// The Writer assumes that all Unicode code points have the same width;
+// this may not be true in some fonts.
+//
+// If DiscardEmptyColumns is set, empty columns that are terminated
+// entirely by vertical (or "soft") tabs are discarded. Columns
+// terminated by horizontal (or "hard") tabs are not affected by
+// this flag.
+//
+// If a Writer is configured to filter HTML, HTML tags and entities
+// are passed through. The widths of tags and entities are
+// assumed to be zero (tags) and one (entities) for formatting purposes.
+//
+// A segment of text may be escaped by bracketing it with Escape
+// characters. The tabwriter passes escaped text segments through
+// unchanged. In particular, it does not interpret any tabs or line
+// breaks within the segment. If the StripEscape flag is set, the
+// Escape characters are stripped from the output; otherwise they
+// are passed through as well. For the purpose of formatting, the
+// width of the escaped text is always computed excluding the Escape
+// characters.
+//
+// The formfeed character ('\f') acts like a newline but it also
+// terminates all columns in the current line (effectively calling
+// Flush). Cells in the next line start new columns. Unless found
+// inside an HTML tag or inside an escaped text segment, formfeed
+// characters appear as newlines in the output.

+
+Colorable writer for windows.
+
+For example, most of logger packages doesn't show colors on windows. (I know we can do it with ansicon. But I don't want.)
+This package is possible to handle escape sequence for ansi color on windows.
+
+## Too Bad!
+
+
+
+
+## So Good!
+
+
+
+## Usage
+
+```go
+logrus.SetFormatter(&logrus.TextFormatter{ForceColors: true})
+logrus.SetOutput(colorable.NewColorableStdout())
+
+logrus.Info("succeeded")
+logrus.Warn("not correct")
+logrus.Error("something error")
+logrus.Fatal("panic")
+```
+
+You can compile above code on non-windows OSs.
+
+## Installation
