@Piinks
Added DataColumn.mainAxisAlignment with new docs and tests, please take a look.

Oh gosh I feel silly for not noticing this earlier. This should probably be crossAxisAlignment, technically. We are talking about the horizontal alignment of DataColumn, for which the main axis would technically be vertical.

Or we could call it headerMainAxisAlignment, since it only applies to the header rather than the whole column. WDYT?

Great observation! I was focused on Row widget inside the DataColumn. I didn't consider what it means for the DataColumn with column in the name.

Sounds good to me. This could be consistent with other header properties if we do headingRowAlignment

flutter/packages/flutter/lib/src/material/data_table_theme.dart

Lines 51 to 53 in 859a5ab

this.headingRowColor,

this.headingRowHeight,

this.headingTextStyle,

I also added this to DataTableTheme.
