<h1 id="column-renderer"><a class="header" href="#column-renderer">Column Renderer</a></h1>
<p>A column renderer is a Lua function that receives a <a href="#table-renderer-argument">special argument</a> and
returns a string that will be displayed in each specific field of the
<a href="layout.html#table">files table</a>.</p>
<p>xplr by default provides the following column renderers:</p>
<ul>
<li><code>xplr.fn.builtin.fmt_general_table_row_cols_0</code></li>
<li><code>xplr.fn.builtin.fmt_general_table_row_cols_1</code></li>
<li><code>xplr.fn.builtin.fmt_general_table_row_cols_2</code></li>
<li><code>xplr.fn.builtin.fmt_general_table_row_cols_3</code></li>
<li><code>xplr.fn.builtin.fmt_general_table_row_cols_4</code></li>
</ul>
<p>You can either overwrite these functions, or create new functions in
<code>xplr.fn.custom</code> and point to them.</p>
<p>Terminal colors are supported.</p>
