flow-table

flow-table is a template rendering application / library for .xlsx file. Pure golang implementation.

HOW TO USE

./flow-table -template <template xlsx file> -data <folder containing data> -output <output file>

template grammar

Write in any table cell:

{{H(.3f)|[js] [data.x, data.y] }}

Next, flow-table will use the js language to execute the expression [data.x, data.y] and render first element in this cell, and extended horizontally (render the second element in right cell), inheriting the same style, and using .3f as the number format.

more abbr:

{{C|[js] data.x }}
{{[js] data.x }}

• expand direction:
  • C: only render in this Cell
  • H: fill cells Horizontally
  • V: fill cells Vertically
  • T: fill cells all direct
• format:
  • s: as a string
  • Xd: such as 10d, integer
